Q Games founder Dylan Cuthbert has gone on record stating that the highly addictive PS3 title PixelJunk Monsters is going to be ported to the PSP sometime in 2009.
PixelJunk Monsters is a tower defense game and the objective is to build defense towers along the enemies path to keep them from reaching a hut. Towers have different attributes such as rapid fire, long range and air focused to name a few. For every enemy that can survive the defense towers and reaches the huts a creature is killed and if all creatures are wiped out you fail the level.
I will be checking this one out when it comes out for the PSP and I hope the PSP titles pick up a little for 2009 maybe this is just the beginning of good things coming out for the PSP.
