On the last level, why does the raze soldier camp and run away? Isnt the planet about to end in 4 minutes unless he kills all the aliens? Not even from a difficulty standpoint, just make the game consistent with the story. 5/5 but still..
Protips for alien campaign: Buy the Holy Grail. Best weapon in the game.
The power extender is really useful for maps with invincibility/double damage because you can grab a shotgun or a launcher and just run through people..
Adrenaline rush is hugely important for later levels so that the raze soldier cant just one hit you.
For those of you worried about certain levels on the Alien campaign being impossible.
level 11 I won with 28-4 with 8 flag captures
Level 14 I won with 32-7 (deathmatch). It can take forever but aim for these statistics and you'll have it.
My only problem was mentioned earlier, that your partner doesnt revive. When I was in the hospital, twice enough zombies came pouring out of the hole in the ceiling that my game lagged and killed me..
So I jump over a crate and gain too much speed and dont see a window, falling to my death. so I hit a crate and then go on a block long building that crumbles beneath me before my slowed player can reach the next building. So I jump through a window only to hit the chair inside and not be able to make the next building. 5/5 for the game that pisses me off the most, its beautifully frustrating
Hitler was actually a very peaceful man.. then he played level 29. @_@. If I wanted something like that, id go play the unfair platformer or take the impossible quiz. other than that, its very good but still..
