It doesn't make sense. This could have been a great game, unless upgrading is nothing more than wasting time. It takes no skill at all. I just wrote 10 lines of code in C# to keep clicking and got all the weapons in no time.
However, 98000 shots with the Kar... well...an 8/10 became 1/10 immediately. You can't even cheat on that! Where's the skill? No skill to get upgrades and even no skill to cheat it!
Oh and for people who doesn't already know, Playing 4 hours gives you 10% more damage... it will help for sure beating the Kar challenge, thanks!
Fix something please, at least make it possible to get a novice medal in the Kar speed challenge, it's the only one i'm missing.
