You and your [Squad/Battalion/Platoon]'s [Helicopter/Transport Plane] crash on a [Enemy/Abandoned/Remote] [Island/Base/City] and there is only a few survivors.
Their supplies are almost depleted the next day, so they have to move deeper.
They encounter some [Enemies/Zombies/Demons] and [Any number or All] of the men were [Captured/Killed/Mind Controlled]. You find some [Crates/Boxes/Bags] full of [Ammo/Food/Weapons/Alien Artifacts]. You see the [Base/City] and enter it.
You find a Radio. You call for [Reinforcements/EUA/Nuke] and then a moment later you are attacked by a stuffload of [Enemies/Zombies/Demons] with only a [Pistol/Assault Rifle/Laser/Shotgun/Rocket Launcher/Chaingun] and [No/Limited/Alot/a stuffload] of ammo. After you kill all the [Enemies/Zombies/Demons], [Reinforcements/EUA/Nuke arrives and you escape. The End.
