I have, until now, never seen a game where the entire game being good or bad hinged on a certain section of a certain level. Don't get me wrong, the game up until that point is barely a 6/10 as it is. I tried the demo and thought well the mixed reviews are probably just fanboys hating on it. Turns out the demo is the only good thing about the game. After level 6 it goes downhill bad. This game is sooooo generic. Painfully bad graphics, animations, and the weapons are horrible. There are no hit indicators when you shoot something or it hits you other than your lifebars decreasing. That's it. The beam is good but the yellow wave weapon is bad and the blue single shot weapon is god awful. So the part where this game finally got a quit/uninstall for me was the graveyard, around level 8 or maybe it was 9. The levels are all recycled by the way. You revisit levels throughout the whole game. So in a certain section in that level it swarms you with blue flyers and yellow ground things and you can't move to the edges or yellow hands will down you. It is probably the hardest part of any game I have ever played. I tried probably 30-40 times for an hour then by luck got to the next section. The next section was the same ♥♥♥♥ing thing: getting downed quickly then the rest of the team gets wiped out. I have seen the game over screen in this game more than any game I have ever played. I don't care who you are, you are going to get downed over, and over, and over again. In laters levels, good luck ever getting picked up by your teammates. They do way less dmg to enemies than you do and if there are enemies on screen while you are down they won't pick you up. They can't anyway because one hit stops the pickup bar and thats it, they are basically dead by getting swarmed.
I have never seen the difficulty spike so fast in any game, ever. If you had 4 real people playing that level might be doable. Might be. This may be the hardest game I have ever played and for all the wrong reasons. All of them.
Crushingly generic, without the difficulty spikes into nearly impossible sections without 3 other human players, this game would barely get a 6/10 from me, maybe a 5.5. With those problems considered, it lowers the score for this horrible piece of ♥♥♥♥ down to a 4/10. Pass on this even if it is free.
