Mckenzie and Perez radioed Banks to assist.
"Roger, Corporal," Banks replied, "Give us a minute, though. There's a problem."
"What kind of a-?" Mckenzie began, but he was interrupted by a loud explosion. The whole building shook, and several loose ceiling tiles came off.
"THAT kind of a problem!" Banks yelled, cutting the radio.
Perez peeked around the corner. "That Elite was the only one there. The rest were Grunts, and I ragged 'em with the grenade," he reported. "But-!"
Another large explosion, and one of the vending machines in the entryway toppled to the floor.
"Wraiths. They picked the perfect time, too." Mckenzie growled. Three of 'em out there, and several Jackals have taken bridge posts."
"Sniper Jackals?" Mckenzie asked.
"Sniper Jackals." Perez confirmed. He opened his radio.
"Sarge!" He yelled, "What is going on? We're sitting ducks like this, and I don't think it'll be much longer before they come waltzing in through our front door!"
"I've just called in for reinforcements; a Scorpion tank and a few soldiers," Banks responded, "but it'll take a while before they get here. Try to return to the roof and rearm. We might be in for a long fight."
"¿Qué es el infierno que pensar?" Perez growled, "It's not even close to safe out there! Even BEFORE the Wraiths popped outta nowhere, it's been dangerous! Now, with their artillery, snipers, and whatnot, he wants us to just turn around and march right back up!?!"
"C'mon!" Mckenzie grabbed Perez and hauled him up the stairs.
