Meteos Wars and PowerUp Forever will be this week's new additions to the Xbox Live Arcade lineup, Microsoft has announced. Both games will sell for 800 Microsoft Points ($10), and both will be downloadable via the Xbox 360's Marketplace come Wednesday.

Continuing in the footsteps of the franchise's previous Nintendo DS and PC releases, Q Entertainment's Meteos Wars tasks players with matching up more blocks of the same color block, though those blocks can only be moved up and down, not left and right.

As for PowerUp Forever, the Blitz Arcade-developed, Namco Bandai-published shooter is a cross between Geometry Wars and Katamari Damacy, with players facing off against a constant wave of foes as their ship grows in size and the world shrinks.

Namco has yet to reveal when the PlayStation 3 version of PowerUp Forever will arrive, but don't be surprised it it arrives with the PlayStation Store update on Thursday.
