The control mechanics behind Robo Rampage are elegantly simple. Movement is dictated by the [WASD] keys while the mouse is used to both shoot and aim. Weapons are selected via the mouse wheel or the [Q] and [E] keys. Like any other good shooter, Robo Rampage gives you a decent array of power-ups and weapons to play with that periodically fall from the sky, but since power-ups to a particular weapon have finite ammunition, you might want to conserve your favourites for boss fights or certain baddies.
While I'm all for the addictive pleasure that lies behind the act of robot genocide, what really got to me about Robo Rampage was the gimmick that they built into it. With every robot that you kill, their bodies will be added to your Kill Hill. It's not really noticeable at first but eventually, you'll find that you'd really prefer a flat piece of land as you attempt to maneuver about during the boss fights and as enemies swarm the bumpy terrain. Of course, I'm a traditionalist; you could play it differently and give yourself vantage points and ravines to work with.
The graphical presentation is excellent, the music is fine and the sound effects and voice acting complements the game perfectly. There's something strangely rewarding about playing a game that somehow manages to combine almost Tetris-like elements with your standard action fare. The only real complaint I have about Robo Rampage is it takes too darn long to get interesting. However, if you're willing to wait, there's a definite gem here to indulge in as you engage in today's coffee break.
