Your mission in this underwater side scrolling shooter with RPG elements is to blast the enemies and tunnel through the rocky terrain. Earn XP points by collecting the seashells. Use the ARROW KEYS or WASD KEYS to move around. Press "Z" or "L" KEY to shoot the pulse cannon (once you've got the upgrade), use "X" or "K" KEY to drill (once you have the upgrade). You can press SPACEBAR to pause the game. Have fun!
