Mega Blast is an action game developed by Crossroads and published by L.K. Avalon for PC (DOS) and Amiga.
The object in Mega Blast is to defeat all of the opponents on the play field. The game plays very similar to the early Bomberman games. Players can place timed bombs that will explode in each direction that is not blocked by an explosive resistant block.
Power ups are in random locations within the blocks that can be destroyed by bombs.
