Halo 5.1 Guardians Of Sera
It has been some time after the events of that transpired when UNSC Fireteam Osiris(for the moment) stopped Cortana's plans to use the forerunner Guardians to in Cortana's words "bring permenant peace across the galaxy".
Unfortunetly Cortana located the UNSC Infinity via a Guardian causing Infinty to retreat via slipspace until they come up with a plan to attack the Guardian.
It's been a few weeks later now and after a while Osiris and Blue Team lead by the Master Chief Spartan John 117 have seemed to see eye to eye about what happened with Cortana and the Guardian. After all it was Osiris who was sent in to bring in Blue Team after going AWOL.
Captain Jacob Lasky of the UNSC Infinity has picked upped a USNC ship that mysteriously crashed landed on an unknown planet.
"Captain Lasky, you may want to take a look at this" said Spartan Commander Sarah Palmer.
"What is it Commander?" asked Lasky.
"We have a UNSC ship that crashed onto an unknown planet" replied Palmer.
"I need details on the ship and the planet" ordered Lasky.
"Nothing in the UNSC datafiles on the planet, but the ship is named "Longbow". said Palmer continuing her anaylisis.
"Have the Covenant or the Prometheans found it?" asked Lasky.
"No reports of activity from either sir" replied Palmer,
"Good, have Osiris and Blue Team come in for debriefing and deployed within the hour" ordered Lasky.
"Yes sir" replied Palmer.
Palmer then called both Spartan teams via intercom.
"Fireteam Osiris and Blue Team report to Captain Lasky for debrief I repeat Fireteam Osiris and Blue Team to Captain Lasky for debrief" ordered Palmer.
Minutes Later Fireteam Osiris(Jameson Locke, Holly Tanaka, Edward Buck, and Olympia Vale) and Blue Team(Master Chief, Frederic Ellsworth, Kelly, Shaddock, and Linda Pravdin) arrived.
"Spartans, approximately 18 hours ago the UNSC Longbow crashed on an unknown planet. Nothing in the UNSC files about the planet's name and we have zero reports of Covenant or Promethean activity. Your mission is to drop in using ODST drop pods and investagate the wreckage. If need be Infinity will follow to establish a base settlement for the time being. We have no idea who or what could be down there. Shape up and stay alert. We have enough problems as it is. You deploy within the hour. Good luck Spartans" said Lasky.
"Yes sir" replied Osiris and Blue Team as they began prepping.
"Osiris and Blue Team on a mission together eh? What could go wrong?" asked Buck.
"Don't jinx it" replied Locke.
Master Chief and the rest of Blue Team arrived to see if Osiris was ready.
"Everybody set?" asked Master Chief.
"Set" replied Osiris.
"No hard feelings 117?" asked Locke.
"Yeah, let's focus on the mission" replied Chief and everyone stepped in their pods ready to deploy.
"Combat drop in 10...9...8...7...6...5...4...3...2...1...deploy" said Lasky via comms.
As both Spartan Teams dropped into this unknown planet they detected human signatures en route to the crash site.
"Detecting human signatures en route to the crash site" said Vale.
"Any UNSC?" asked Chief.
"Negative" replied Vale.
"We better hope we beat 'em to it" said Buck.
"Agreed" added Locke.
"Jesus anyone else getting visual on the landscape?" asked Tanaka as she noticed the barren wasteland.
"It's a miracle any other humans survive here" added Fred.
"I'm surpriesed any humans are even on this planet" said Kelly.
"Approaching the ground" said Chief.
"Brace for impact!" shouted Linda.
Everyone crashed and scattered near the location of Longbow. Buck however got the worst part of the landing.
Buck seemed to crash cliffside as his pod was about to fall.
"BUCK! status!" ordered Locke via comms.
"Uh I crashed my pod cliffside but I do have visual on Longbow!" replied Buck.
"Everyone regroup to Buck's location double time" ordered Chief.
"You might wanna make that a triple time" added Buck.
"Why?" asked Locke.
"Those "human signatures" from earlier have air transport and they're about to land to the site" answered Buck.
"We're en route" said Chief and Blue Team and the rest of Osiris quickly regrouped with Buck. Luckily everyone wasn't far and neither was the route to the crash site.
But with Osiris and Blue Team in pursuit. There were others who took notice of the UNSC Longbow.
Author's Note: Alright hello. This is a Halo/Gears Of War crossover based on and inspired by "Spartan Gears" written by BlackSuitChris. It was by far the best Halo/Gears crossover fanfiction I've ever read so props to the guy.
