Cubic Exploding Goro
From the Pointzero Company, Cubic Exploding Goro is nearly as strange as the name suggests. This 3D action game from Japan puts you in the shoes of Goro, a grim angular anti-hero in a violent, polygonal Shockwave-powered world.
Run around each circular stage by pointing the mouse in the direction you want to move. Hold down the left mouse button to begin charging an explosion. As you charge the button a red field will grow around you; release the button to create an explosion inside the field, damaging any nearby enemies. Naturally, a larger field results in a larger explosion. Goro is vulnerable and motionless while powering up, but a decent sized explosion will launch him far into the air, avoiding any incoming lasers, bullets or giant enemy tanks. Press S to toggle sound on and off, and P to pause the game.
Analysis: Cubic Exploding Goro is weird, fun and, with over 24 levels and a wide variety of enemies, quite challenging. However, it is not an attractive game. The metallic rotating fonts are garish and the primitive 3D models look dated. There's charm in Pointzero's funky lack of style, though, and Cubic Exploding Goro is a great and unique arcade experience.
