Hi guys, came across this thread while doing a quick search to see if anyone needed help with the game. I've posted a walkthrough on my site that I will update according to the questions that I get. So if you would like a specific question answered please comment on it at my site and I'll do my best to reply quickly. Thanks!

This may be as cheap a shot as resetting and firing, but for the SMG-PK2 fire three shots (click 3 times quickly) at the lowest crate such that all three bullets come out at the same time due to lag or something like lag. It works every time if all three bullets come out at about the same time.
the hardest one for me is the one with the shotgun spas, 2 seconds to win it. you have to get a lucky knockback :P oh and i did every challenge, im currently working on getting the kar to 98... 980 :O lol
