First of all i love this game, i love the fact that you need to work yourself to the top (by saving up cash for a knife, or then for a teammate) the game is very fun and addictive (found myself playing it 2 days for 5 hours nonstop)
But the thing that annoys me the most is the fact that LAG KILLED THE GAME !!
I got to wave 44. By then there are to much enemies on screen to make the game LAG LIKE HELL!
I got a fully lvl 70 upgraded character with the best armor, yet i got killed. Whole my team got wiped out (no prob, they were just mercs) but i got killed because all the lag the game caused, i could let my keyboard go and the guy would go on for another minute without any command.
Please, fix the lag. I run the game on LOW grafix with a gaming rig and good internet.
Just the game isnt able to cope the many enemies at the later waves.
otherwise it got a 5 star rating
sorry for the bad english
