(AN: so i decided after about 10 months to get to work finishing this fan fiction with the chapter already post to be modified)

A spinning ADVENT logo appears on a red Cityscape background which then changes to a woman with black straight hair in ADVENT clothing with a video of ADVENT soldiers marching which then changes to mecs doing the ADVENT salute as text written in an alien language stroll across the screen.

"Excitement continues to build as city centres across the globe prepare for the 20th anniversary of Unification Day." The women said.

It then changes to a different news message with a different woman this one having blond hair and grey and white clothing and text scroll was in English this time with four different videos of an ADVENT city with tow showing what looks like a metal detector and one show a screen with the ADVENT logo on it.

"Thousands line up at the site of the Great Accord, celebrating the formation of the ADVENT Coalition." Said that woman.

It then changes to a man with black hair and black and dark grey clothing, with a blue text box with yellow alien text with a red with blue border text box above saying '20 YEARS OF ADVENT' with a video of an ADVENT captain which then changes to the outside of a gene therapy with some ADVENT soldiers, then showing the inside of it.

"In keeping with their promise to humanity, 12 new gene therapy clinics will be opening in select cities by the end of the new year."

It then switches over to another lady with black hair in a wave style, with the video showing an attack on a gene clinic then it changes to the entrance to another gene clinic with ADVENT troopers guarding it.

"despite the attack by fringe elements, operation at the new facility in Paris thankfully remain unaffected." Said by the woman.

It then shows a black man with grey hair with the text box style change and showing a platform with cameras and troops guarding it.

"In response to the unprovoked intrusion on the eve of our most beloved celebration, the Speaker reaches out to us…" the man said.

Then it shows a man with thick sunglasses and ADVENT clothing (The Speaker) as he stepped in front of the ADVENT logo to begin talking to the public.

"A small number of dissidents again repeat the mistakes of the old world. Striking as we celebrate a benevolent saviour who time and again offers only friendship and compassion. Yet these trivial actions could never break the bond between humanity and the elders…" as it shows ADVENT troops fight against rebels and, right at the end, it shows the elder statute.

"Peacekeeping force have already made several preemptive arrests of known collaborators." One of the news woman was talking as ADVENT troops storm a house armed with live weapons.

"ADVENT again assures all citizens that today's celebrations will continue as planned." As the screen changes to continue to show police brutality as people were watching it on a large screen in the public area but after it finish one man turns away.

"Perfect." He said

"The ADVENT administration reminds you to report all suspicious peoples to your nearest peacekeeper. Remember, only together can we build a better tomorrow." As the news continued on and as a lady walked down the street she brought a hand up to her ear as ADVENT was investigating someone on the street.

"Approaching position." As she said to an earpiece as she walks to an ADVENT police blockage.

"Prep Gatecrasher, 60 seconds." The man said.

As the man was in the queue with a scanner at the end. When he went through it sent off an alarm with all the ADVENT soldiers and the captain going over the man.

"Mor Balaten." One of the ADVENT soldiers said.

The ADVENT captain hit the man with the butt of his rifle which caused him to fall to his knees as the woman went over to one of the vehicles and place an explosive on it and got away.

"Mor Balaten." As the ADVENT soldier kept saying the same thing to the man, he saw the woman walk away from the vehicle.

"Now." The man said.

As the woman pulled up a detonator and pressed the trigger blowing up the vehicle and sending the ADVENT troops flying.

Then at a resistance base.

"Signal received loud and clear" said Shen as it shows the area with a blue tint which then pulls out show more of the holo-table and the person talking, it then shows the inside of the Skyranger. "OK, Gatecrasher, your turn."

As the Skyranger flew through the city the XCOM operatives got ready for the mission.

Location: ADVENT Security Ward, Tijuana

"Now that we've got a foothold, it's time to take the fight to ADVENT. We're heading into the city centre to take down a public target, something that will get people's attention. Neutralise any security forces in the area – keep your head down." Central informs the operatives.

'Operation Gatecrasher'

'BRIEFING: Sabotage ADVENT Monument'

OBJECTIVE:

Neutralise all enemy forces

Plant X4 on the monument

Soldiers:

-Chuck 'The Duck' Miller (rookie) an American white male with brown hair and a pair of aviators with the standard beige Kevlar armour with black highlights.

-Lara Lemmings (rookie) an Australian white female with brown hair and purple Kevlar armour and light grey leggings and pouches.

-Ivan 'Cypher' Ivanovic (rookie) a Russian white male with black hair and wearing a beanie and eye pack with red and black Kevlar armour and a custom red rifle.

-Mitchell 'Nytmare' D (rookie) a British white male with blond hair in a ponytail with green Kevlar armour with white highlights and pouches.

All of them having a standard assault rifle

The soldiers were set down on the road leading to their target, a gold statue of an elder, with a building to their right and a parking lot to their left.

"OK, let's head over to that building Chuck have a look at that building and then if clear get into the rooftop. Also you're at the biggest risk because this is my first mission as commander and get to the statue and eliminate the enemy. The statue is ugly and the ADVENT isn't any better so it not a big shame" Commander Faleg said to the soldiers.

"Orders confirmed, on the move." As chuck ran over to a street light. "I see a climbing point." He said as he got closer seeing a gutter pipe which led to the roof.

"I will go next." As Lara ran over to join chuck by the side of the building being closest to the gutter and soon after Ivan going between and Mitchell.

"I will go first up the building." As Lara got on top of the building with some ventilation and some Barrier and railing and got behind a barrier facing west with Ivan and Chuck, Nytmare going to a barrier behind them and being on the side with the ventilation covering his right flank. Lara the when a bit further over to the side of the building closer to the statue first going over to a vent and then to a piece of railing at the corner.

As Lara looks over the area with at least four civilian two by a lesser statue and two by the building, both talking to each other and a truck to the east of it with some barriers in-between the statue and the truck and to the west there was a Security Tower. Then Chuck and Ivan went over to join Lara and Nytmare going over to the other corner, then they saw three ADVENT troopers standing around.

"these guy make up the bulk of the ADVENT forces we've dealt with. They're disciplined and well equipped, but their obedience makes them predictable." As Central informed the soldiers over the comms.

"let's get over to that truck we can ambush those troopers." Mitchell said to the others.

As Ivan and Chuck made their way over to Nytmare, Lara stayed over to her side to keep watch. Chuck then jumping down to a café area and then to a bus stop. Ivan and Nytmare going to the short wall surrounding the café with tables flanking them from their sides with Lara coming over to Chuck by the bus stop with her getting very close to the civilians. Then Chuck went over to a barrier separating the two roads with the others joining him and they went over to the truck but by the time they got there the troopers were gone.

Then Chuck went over to a barrier and saw where the troopers went to with one of the troopers by the civilians. Lara then went to another barrier and saw another ADVENT trooper and one of the evolved Sectoids.

"Although they bear some resemblance to the Sectoids first encountered, their genetic structure now includes human DNA. They're stronger than ever, with an even greater psionic potential." As doctor Tygan informed them about the Sectoid.

Then the troopers walked closer to the Xcom operatives with any movement alerting them. Nytmare and Ivan got read to open fire as Lara readied a Frag Grenade, then throwing it towards the two troopers who were by a bus stop, killing one of them, then Nytmare gunned the trooper down blowing it brains out, Ivan killing the last of the first group of troopers but leaving the Sectoid and other trooper alerted to their position with them moving to take cover behind the bus stop. Chuck then ran over to a flower pot and threw a Frag Grenade badly injuring the trooper. the Sectoid the ran over to Lara and used an ability which used to belong only to the commander subspecies 'mind control' as purple psi energy tentacles went over from the Sectoid's head to Lara's head, taking control of her body. While the trooper ran to another flower pot and opened fire on Nytmare, badly injuring him.

"Can't fight it." She said struggling to fight the mind control.

Then Nytmare, despite losing a good bit of blood from the trooper shots, threw his Frag Grenade destroying the Sectoid's cover with Ivan following up with some shots from his rifle killing the Sectoid and breaking the mind control over Lara lemming. all while Chuck moved up to the trooper, but then Lara ran up to the trooper and shot the trooper killing it.

"target eliminated!" As Lara took out her frustration on the trooper after the mind control.

"OK, let's move towards the objective." Chuck said as he and Lara moved up to a bench closer to the main statue but when Ivan moved up to the lesser statue he spotted 2 troopers and an ADVENT captain who then moved in.

"The ADVENT officers seem more capable than the grunts. We're not sure whether it's up to training or stricter mind control." As Central comment on the officer.

Nytmare moved to a column and then scored a great hit on the officer with Ivan finishing up with his Frag Grenade. Chuck and Lara got ready for the trooper and when it moved forward Chuck missed but Lara hit. But, it was not a kill with the trooper trying to get a shot on Chuck, but it missed. Ivan then went over to the trooper's flank

"You have a bee on your face!" Ivan said in Russian as the trooper looked confused Ivan shot him in the face with the confused being the last thing on it brain before losing it.

"Area is secure – we're not picking up any inbound contact, scanners are clear." Then Central followed up with "GateCrasher, we have a limited window to act before ADVENT responds, we need to get those charges planted on the double."

As Chuck went over to the statue and planted the X4 charge.

"GateCrasher, rendezvous at the extraction point." As Central gave the last order to the troopers.

"let's gather the corpses and get them on the Skyranger." Chuck gave his order to the other.

Once they had gather the corpse and called the Skyranger, Lara threw the Sectoid corpse with total malice.

"Lara can you please not destroy the corpse it is the only Sectoid body we have." Tygan reprimanded Lara for her taking her angry on the Sectoid.

"Fine then." Lara sighed out an angry sigh. She helps load the Skyranger with the dead bodies after it got into the sky.

"Status confirmed, squad is clear. Detonating charges." As central had the X4 charges detonated, bringing down the statue.

"Hey Mitchell how are you doing, you took a nasty hit from that trooper." Ivan asked Mitchell as he helped patch him up as they went back to the avenger.

As it proceeded to land all four got out of it with Nytmare collapsing from his injuries.

After they got in, they reserved for all promotion Chuck being made a sharpshooter with a long range sniper rifle and a high calibre pistol which could kindly be call a hand cannon.

Mitchell got to be a ranger with a shotgun and a machete-like sword which can prove as a useful close combat weapon. But because of his injuries Mitchell became shaken with weaken will.

Lara became a grenadier with a Cannon which was basically a mini-gun and Grenade launcher for heavy ordnance delivery.

Ivan got to be a specialist with the remote hacking drone that can be outfitted with combat or field medic duty 'GREMLINs' and keeping his rifle.

Commander Faleg chose that the best research option to be was 'Modular Weapons' to allow parts of ADVENT weapons to be used to make the XCOM weapons stronger. Also the commander had the Guerrilla Tactics School construction started.

With all that has happened it was time for humanity to gain its freedom from its alien master.

XCOM LIVES.

(Omake)

After the mission

"So we came build a Guerrilla Tactics school commander, commander." Shen was talking with commander Faleg about what could be built in the free room in the Avenger

"So we can arm gorilla with shotguns and send them at Advent." Faleg said with a excited sound in his voice about his 'plan'.

"Um Commander, it guerrilla not gorilla and i don't think we can get them, yet alone train them to uses shotgun we barely have enough equipment for our own troops." as Shen was a bit dubious about the commander's 'plan'.
