Sad to say...I never finished the game because I couldn't even get past the first couple minutes of it! It's basically right away at the beginning of the game when they are in the building and they supposedly call for back up. Was back up ever supposed to come? Because my sister and I were completely overpowered by the hoard of zombies that would keep coming, despite us killing multiple Executioners XD
My sister was flipping out because we lasted about twenty minutes before finally giving up.
We pretty much failed...
No there really is no backup lol. Basically what happens is you fight off the horde of, there not really even zombies more like mutated humans, zombies for like 30 minutes. No joke. Until you hear the guy in the chopper say ok find some cover. He blows up the gate and you progress thru the mission.
To remove oneself from the equation. To know that as long as my eyes are black; I'll never lose.
