The game is awesome.
The only thing that some might find negative is that the alien campaign is near impossible, I had to try it at least 100 times before I could beat it.
The reason why it's so difficult is because the zombified Raze Soldier has about 5 times more health than you and your team mates feed kiils to them so it's reaaaally difficult
HOWEVER, unlike the first game it is not just straight up impossible so yay
The hard achievement needs to be changed to impossible
Your bots are 1/5 of the enemy bots plus at the last level raze soldier likes run around wasting time for the meteorites plus he spawns with a rocket launcher and has twice the health of a player with armor
I just hate when there is one troop wich fights, and the other ones just stare instead of helping him kill the enemy, i have to move them really close to the enemy in order for them to help the other troop.
I found a glitch: If you have the upgrade to get some Rush pts when you get a max rage launch if you spam the Spacebar when it says " Maximum rage!" you get a lot of rush pts depending on how many times you spammed the spacebar.
