A new update for Comet Crash, the popular tower defense game from indie developers Pelfast, is now available on both the US and European PlayStation Network.

The content patch (1.03 update) introduces new levels and maps as well as new battle settings and even a new difficulty mode. The full list of features follows below:

• “Expert difficulty setting for seasoned Comet Crash players. You’ll see a surge in enemy attacks that will put your skills to the test.
• 4 new Resurgence levels–one unlocked at the end of each comet during the Campaign. Resurgence levels may require completely new strategies. Beware…no hints!
• 4 new Battle maps to mix up your games a bit.
• Battle timer setting. After the timer runs out, all mobile units generate at 8x the normal rate which should bring games to an exciting finish!
• Thorium setting to tweak available resources in Battle mode.”

Comet Crash sees players building towers to defend against waves of enemies and unleashing swarms of their own troops to unleash havoc on the enemy. Up to three players can fight through 28 levels in the campaign mode while battle mode enables you to take on up to four friends offline.
