The above screen grab may not be rather enticing to you, but that's because it's from a rather stylistic trailer for the upcoming Fireteams mode for Combat Arms, a free online FPS from Nexon.
The Fireteams mode is an 8 player cooperative mode that will be added to the game on May 27th. There will be various objective based scenarios like hostage rescue and bomb defusal. As we said, Combat Arms is already free, so this additional free update is pretty awesome in our book.
Having played some Combat Arms in the past I can say it's definitely worth the money. Seriously though the game is a pretty decent quality shooter that's a lot of fun to play. And you can't beat the price.
