Virus-Free?*: Yes, just don't download the "Matrix Mod". It's been proven that it contains a trojan. As long as you don't get it form the mods page, you have nothing to worry about.
Okay so maybe this one isn't on the consoles. It's actually a flash series, and they have a game released now. It is quite easily one of the best flash games ive ever played, even more so than Alien Hominoid. It's just so damn simple and so damn fun! There is a story, but you have to watch the first 3 movies to find out, or just skip ahead to the game.
Concept: You're looking for the Sherrif. It's as simple as that, folks. Blast your way through armies of minions preventing you from going any further.
Graphics: Though it is flash, The game has a certain style that makes it all fit together.
Sound: Sound effects for a lot of stuff, and the music is good too!
Control: VERY simple interface. You'll have no trouble getting used to it.
Overall: I know, It's not as good as the consoles, but it's still one of those games that you can't help but enjoy. Though it has a plot, it isn't explained well, even for flash, and if you're not into the whole mindless action thing, you may not want to venture near this one. For all of you programmers though, the Source Code IS available for download, if you want to make your own mods.

*I put the virus-free notification because there are some here who are very cautious about what they download, and I totally understand.
