Maybe it's because it's a console port or something but i found the controls to be highly unresponsive and the game becoming incredibly tedious at times. Any combo that requires more then one button fails 90% of the time because apparently the grace period for hitting the second button is measured in nanoseconds and Alex picks one of the simple attacks at random. As for the gameplay, hitting people with various overgrown extremities for five minutes is fun. Jumping at helicopters for half an hour because they keep calling them in faster then i can kill them and all of my sky attacks being as accurate as an airsoft gun in a hurricane is NOT. Especially not when after dispatching all of them i hit another fucking uav on my way to the doorway where i was before i was chased out by a bunch of self replicating birds because i can't enter with them around and have to do it all again. When they work, some of the minigames are fun, some are insultingly easy(the jump ones) and others are downright impossible due to bad controls(driving an APC around for 2 minutes with groups of 10 rocket troops spawning right behind you every 5 seconds and firing a volley of 60% health missiles before i can even get the turret around halfway). Another bug is that when i got a mission to bombard some zombies with a heli i flew up high and opened up on the streets below with the rockets. After the 120 seconds were over, i had 4 points. I tried again but while hovering 10 ft of the ground and got some 300 odd kills. A bug/console leftover that prevented bombs from hitting the ground. Around the time i got the infection detector upgrade, i glitched out the game by destroying a base at exactly the time i died, resulting in it collapsing as i respawned and ending up with an undead base that looked destroyed but had a completely unaffected interior and outside presence and was no longer targetable, which resulted i me getting stuck when ordered to destroy it a few missions later. At which point i couldn't be bothered to put up with the first half of the game again and i uninstalled it.
I can see this being worth $10 or $15 with the bugs fixed, the console related limitations removed and the controls improved but right now I'm happy i pirated it instead of wasting any amount of money.
