The world just has too few mech battlers these days, with fewer still existing on the current generation of consoles. If you've had a hankering to crush puny ground troops (and also other mechs) with your pulsing, mechanical fists, then you could do plenty worse than the action/strategy experience in AirMech Arena. For example, you could play Steel Battalion: Heavy Armor, otherwise known as Claw Your Own Eyes Out 2K15.
The release schedule on XBLA may not be as busy as it once was, but there are still quality co-op games being released on the platform. AirMech Arena is a good example. This 4 player co-op free-to-play RTS has exited Beta and is now on official 360 release.
If giant transforming robots of destruction are your thing (insert Michael Bay reference here) than AirMech Arena might be right up your alley. This free to play title combines the fast pace of a top down shooter with real time strategy elements, while also throwing some MOBA action into the arena. AirMech Arena, from Ubisoft and Carbon Games, will see a release this summer on Xbox 360, but not before the closed beta which runs July 23 - 29.
Summer is a mere month away, meaning another Xbox Live's Summer of Arcade is sneaking up on us. Of course, we don't know which pick up and play games will be included in the promotion, though an Xbox 360 only release with the release date of "Summer 2014" might give you a hint. Speaking of which: AirMech Arena is dropping this summer for Xbox Live.
