Battle Bull — About this game
Drive the Battle Bull dozer through a 48-level mine, crushing dangerous bugs with movable ore blocks. Fixed blocks constrain the routes, and pushing one block into another can destroy it, so each attack also changes the arena. Earn gold from cleared stages and buy engines, shovels, extra lives or equipment that adds jumping and weapons. Clear the required enemies before reclamation units seal the area. Press A for one player and inspect the maintenance shop before descending. Practise pushing a clear block into the first bug rather than trapping yourself against fixed rocks. In the shop, SELECT displays a password.
