It seems that this was a pretty big week on the Steam Store. Not only did the new Call of Duty hit, but also the renowned Arcade developer, CAVE, has made its Steam debut with their hit "bug princess" shooter, Mushihimesama (mooshee-heemay-sahmah). Additionally, SEGA graciously saw fit to bring over their previously Nintendo-exclusive Sonic the Hedgehog game, Sonic Lost World.
I don't know about you, but the CAVE news alone was enough to send me to gaming heaven (before their punishing shooter promptly sent me to bullet hell). Proceed further to see more of this week's new releases.
