Play Contra On

You can now play the classic game of Contra on I’ll have to warn you though, it is pretty addicting. It comes complete with cheat codes (yes, even God Mode if you wish).

Amazingly this has only received a 52% rating when this is the best flash version of Contra that I have ever seen. It has multiple difficulty settings, image quality settings, and the ability to customize what keys you want to use. This will do more than kill some time, it will bog down your day!
