March the 16th sees the latest backward compatible title from the Xbox 360 become available via Games with Gold, and it’s Heavy Weapon. This side scrolling, twin-stick (ish) shooter was released way back in 2005. You play Atomic Tank, battling through several stages with various military hardware of the Red Star (yup, it’s those pesky Russians again) trying to stop you reaching a end boss. Between rounds you can upgrade your tank to increase your defense and attack in various ways. It’s a fun little time killer, in the same vein as Geometry Wars, Trials HD and the like, and perfect for a quick blast away from games which require more focus and attention.
