Robocco Wars

In this game you control a manoeuvrable robot on wheels, armed with a powerful cannon. By choosing upgrades, you can improve your weapon and your health. When you reach the end of a level, our robot transforms into a shuttle or a submarine. In total, there are 5 ground, 3 flying and 2 underwater stages in the game. The graphics are bright and cartoonish, and many of the mechanisms have cartoon eyes and mouths. The difficulty level is not at all childish: the first 6 levels are fast, and from the 7th level the cunning of the ringleaders increases. If you die, they'll take your weapons, and if you waste your continuation, they'll take your health, so you won't be able to pass RW in a hurry. Fun game.
