first ad foremost: dark magic didn't block my server, I'm just to awesome for the server, there is a difference...
Second: there should be a % meter next to the contracts, because now it's a mess
Good game, but huge downsides:
-the more expensive weapons are usually worse: loadtime or number of units you can take out with one round
-once you buy a weapon which is basicly useless but expensive, you can't sell it, nor UPGRADE it
-If your low on cash: tough luck (this really blows)
Hint: you can beat the first 15 levels with just weapon 5 and 6
