Easily my favourite shared screen pvp game ever. It's a combination of Mashed (or speedrunners for a more modern reference), Liero and Super smash brothers. Can't recommend enough. Would suggest using a controller though - playing on keyboard is a little funky and rebinding keys takes a few tries to get right. If you play competitive mess around games with friends, get this.

Solid game, essentially BF3 again but the multiplayer has enough going for it such as 'assignment' to keep you playing for hours. Also nice new vehicles and they've done well to add plenty of variety in terms of maps when it comes to the expansions. (although single-player was dismal)

Used to play this game when it was just a CS:S mod and it's come a long way since then. It's an unforgiving realistic game that's actually fun to play (unlike the arma series in my opinion). The objectives are clear and games can go from a minute or two (if you are lucky/unlucky) to 20+ minutes. For $15 this game is well worth it.

The game has lots of variety, and even accommodates for different play styles which you wouldn't expect from a game such as this. Lots of fun, I can only hope i can convince my friends to buy it.

The Showdown Effect is a brilliant Death-match or TDM game for friends and strangers alike. The game has no single-player and possibly could use one however the game as it stands is heaps of fun and is very challenging. Unfortunately the community is quite small so if you are interested i highly recommend you get this game with friends. I love this game and i'm just sad that it doesn't have a community as big as it deserves.

Very fun game, it's very entertaining - challenging enough to keep it interesting with lots of diversions to do to mix it up. Wish it had more online stuff like team death matches etc but Co-op is still hilarious. One thing i feel which isn't as good as SR2 or even other GTA games is the radio - not particularly funny. Still though, love the game - pick it up and go nuts, perfect to play in conjunction with a serious game. For example, i'm currently playing this and Skyrim. When i get a bit bored of streaking challenges i'll do some quests in Skyrim and when i get bored of those quests i go back to SR3. Perfect balance :) Great addition to the series.
