PolarBit is now slowly releasing some of their old games for FREE and this includes two of their previously popular titles - Raging Thunder and Wave Blazer. Wave Blazer itself isn't a full game but rather a lite version with a single level for single player & multi player mode.
On the other hand, Raging Thunder is the FULL version of the game iteslf with nothing being stripped off except that it contains ads. The full paid version of course, does not contain ads. You can grab both of these great games from the Android Market links below:
