Alien Zombie Mega Death invades this week's PlayStation Network downloads

It's a light week in terms of new games for PlayStation users as a few casual PSP mini titles and a shoot 'em up comprise the latest offerings.  However, there are some major DLC additions debuting today such as a map pack for Killzone 3, the Skarlet character for Mortal Kombat, and a fresh L.A. Noire case.

PlayStation 3 games and demos:

• Alien Zombie Mega Death sees a lone spaceman face off against hordes of invading aliens in 70 stages. The brave astronaut has a few gadgets to help deal with the aliens but he also must keep an eye out for space babies to rescue and bombs that need defusing.  Save the galaxy for $7.99.
  
• For tennis fans, Sega offers a Virtua Tennis 4 demo today.  This sampler shows off support for PlayStation Move controllers and 3D televisions.
  

PSP minis:

• Brick Breaker is a Breakout clone featuring power-ups that can help or hinder your block-breaking progress.  A Dual Paddle Mode places a paddle at the top and bottom of the screen.  Break some blocks for $3.99.
