The strafe accuracy has decreased significantly, please revert this aspect of gameplay. It is better to camp now than it is to move, since moving will both bring you into unfamiliar places, and give you the disadvantage by rewarding you with awful accuracy and giving campers the greater accuracy advantage. Jumpshotting can be taken out, but there needs to be a way for noncampers to have a level playing field with spread in using their weapon.
I usually get around 20-30 FPS with a decent computer that I get 95-100 or more FPS on CS Portable. I have a 2.7 KDR in CS Portable, but when you get a low framerate in this game, you still have a horrible amount of aim smoothing which can be very inconvenient to many players. The aim smoothing remains high despite the use of all options to optimize the experience. Other than that, keep updating! Good progress!
They should create an explosive/search and destroy/sabotage mode where winning teams get coin and exp bonuses at the end of the round, and their raking is shown on the screen at the end of the match to make people more conscious of it.
The maps need to be bigger, more complex, and we need more teammates. Make the maps like boxhead: more rooms. It's a good zombie game too, but this game has a better mmo element.
