~~THINGS TO IMPROVE ON~~
Could be a little less laggy maybe due to everything going on
I remember playing this game some years ago and back then it was one of my favorite games, among many others of the same developer. It's sad that he appearently stopped making flashgames. I hope that, whatever he's doing now, he's allright. And maybe one day he'll be back.
Now, regarding the game itself: It's got pretty much everything you can expect from a good flashgame. A lot of weapons and upgrades (perks), many different types of enemies, pretty fluid combat, etc. Only bad thing about it is that sometimes it can get a little bit laggy, but that seems to be normal for shooter flashgames.
