Iceblaster

Iceblaster is a shooter, created by Christoph Cemper and and Stefan Hartwig and released by Dome Developments in 1994. This is a horizontally scrolling shooter, set in a cave system where you need to simultaneously avoid the stalagmite and stalactite formations and also fire furiously at the oncoming aliens. Each time you hit a rock formation, energy is drained from your shields. When you hit an alien you can recover a small portion of that energy but if you run completely out you will be destroyed.
