Tenchu Z demo sneaks onto XBL with all the stealth of a … um … something …

Maybe I missed the announcement, or maybe this was some clever bit of performance marketing on the part of Microsoft, but the demo for Tenchu Z seems to have appeared out of the shadows and is now available on the Xbox Live Marketplace.

Based on pre-release footage, and everything we’ve heard, we’re less than excited about the title, but ninjas innately have so much potential for stabbing your head off with swords made out of pure awesome, that we just had to download the thing.

Reactions so far? Is this the new Ninja Gaiden of sneak-em-ups, or is it merely Wrath of the Black Manta-level ninjery?
