Great game plagued by ads
Like everyone else, I hate that damn link in the corner and the credits. Corner link kills you, and if you're trying madly to survive you'll open the endgame link over and over which gets annoying. Aside from that, the bodies glitch sometimes- I got stuck in midair and had to use nothing but psy for an age until I was pulled out, I'll get rocketed up places if I move an inch... Plus, there was no way to get back grenades, but they were worthless anyway because they take an age to blow up, you can't aim them, no midair throwing either. And the jump is awful, it's bugged up to hell with jumping anywhere other than up and if you jump just up all the clone swarm under you and swing so you die on the way down when you can't attack.
In summary, FULL of problems but still very very enjoyable. Duals are great, you don't die until you get bored, lol.
