MadMaks is a promising robot-combat arcade game with chunky old-school graphics, fun controls, and a short solo campaign.
You start the game controlling a maneuverable but relatively wimpy tank--a "Frogamo Mak"--and you can opt for good accelerometer controls (tilting left and right to steer, and forward and back to move) or a somewhat clunkier virtual directional-pad. You change weapons and shoot using touch-screen buttons, as you travel across a 3D sandbox terrain, destroying and defending various targets (all as cute as your Mak, with similar cartoony eyes) to accomplish varying objectives over 10 unlockable levels. As you complete each level, you unlock the next level and earn stars based on your performance--which then unlock new "Maks" for replaying earlier levels or taking on one of five "Challenge Games" (from a straightforward Survival mode to a timed spot-the-differences challenge). Along with three different difficulty levels, these new Maks provide much of the game's replay value, letting you pilot the Rabbido Mak (a speedy, twin-blade helicopter), Wolftone Mak (a VTOL bomber), and Beargang Mak (a beefy, stomping Mak with a cannon for a nose).
MadMaks provides a pretty fun arcade experience, reminiscent of early fifth-generation console games, but the game is crying out for a multiplayer mode--which the developers promise in future updates. MadMaks is a decent value in its current incarnation, but should become much more popular with the addition of multiplayer.
