A new (and free) title update, now available for the PSN-exclusive Comet Crash, introduces new levels, maps, battle settings and an "expert" difficulty mode to the Tower Defense-style game. What sets Comet Crash apart from other titles in the genre is the game's offensive gameplay, allowing players to send waves of their own forces against an ongoing alien threat. Aliens as enemies in a video game? Creativity! According to the PlayStation Blog, the 1.03 update includes:

"Expert" difficulty setting for seasoned Comet Crash players.
4 new Resurgence levels -- one unlocked at the end of each comet during the Campaign.
4 new Battle maps.
Battle timer setting. After the timer runs out, all mobile units generate at 8x the normal rate.
Thorium setting to tweak available resources in Battle mode.
