Playing on Kiznitt's XBL account. Had to wait for it to cheapen up a little but now it's ours. So far, the Dig Site and Farm are the only major missions we played. We ended the session in the Hospital. Skirmishes play out with a good balance of reflex and strategy. Upgrading weapons and skills: awesome for the FPS genre. Upgraded the sniper rifle a lot but ammo seems more scarce for it. We like this game so far.
