Could we get Alternate Endings, so that if you play the campaign multiple times, you can see a little more of what happened, and possible something else changes? I'll give an Example...
This first playthrough shows: Your on a shuttle, you try to escape, but it explodes, THE END!
The Second Playthrough Shows: Your on a shuttle, You try to escape, you see a wounded comrade with a crazed phsyco getting ready to slaughter him with a Crowbar. You get into a fight, and you win, you find a Spare Pod that can only seat one person. You then choose whether you want to leave your friend on the ship and flee with your life, or if you want to save him, and let yourself parish.
The Thrid Playthrough shows: Your on a shuttle, you try to escape, you find an Emergency Fail-safe that will seperate the damaged ship from the rest of the shuttle, you and your comrade escapes back home, but the Crazed Phsyco is now on the loose, and now is more dangerous since he has taken a vile of experimental Substance, he transforms into a horrifying beast, who inturn causes mass Destruction and makes the planet a Living Hell. You see women and children being killed while fire plunges around everywhere. You should feel proud for yourself.
The Fourth Playthrough Shows: Your on a shuttle, you try to escape, you manage to land the shuttle into an unknown planet, you and your comrade are the only survivors on an empty planet, you rebuild the ship with supplies found on the planet, and mange to make it back home. Happy ending! YAY you diden't cause a mass Extinction!
Just something to give the game a little twist, kinda like Dead rising, with it's different endings, like 5 or 6 I think.
