As if it wasn't enough to get the chance to spend today playing a fake game of big-head stickball, Microsoft is adding two -- count 'em, two -- additional games to the XBLA service today. First up is Tenchu: Shadow Assault, a multiplayer ninja game of some sort based on FROM Software's long-running series. Just like a ninja itself, this game really came out of nowhere, and could quite possibly kill you in your sleep.
The second, Beat'n Groovy, looks like Konami's long-running Japanese series Pop'n Music, but, against all odds, has an even worse name. You can pick them both up for 800 points ($10).
