theevil11's review is an insult to the author.
To previous reviewer: just because you saw it on heavygames before doesn't mean it should be libeled stolen, you dumbass. Even though the game credits the authors; Mindchamber and Psychogoldfish, who are respectable flash artists that made plenty of quality material in the past. That's like saying Leonardo stole Mona Lisa from ebaumsworld just because it had an ebaumsworld logo. God I hate stupid people.
As for the flash there's nothing much to say other than it's spectacular, however the controls are sluggish at times and performance drops down at higher levels of action. There are some gameplay problems as well, fighting options seem limited, and it most of the battling early on could be easily won with the minigun. Even though I don't usually like these types of games, there was much effort and skill put into it, so congratulations on that, and I hope to see a continuation in the future from the authors.
