Humanity is under attack by malevolent spirits. Now it's up to a brave man named Bill, armed only with his wits and a hammer, to defend against this invasion.
In Cosmic Crisis , players control Bill as he navigates through levels filled with brick platforms connected by ladders. The objective is to punch holes in the platforms with his hammer to trap ghosts. Once trapped, Bill must reach the ghost and continue hammering until it falls through a hole and is destroyed upon impact. Different colored ghosts require different numbers of falls to destroy them. With time running out, Bill must eliminate all ghosts in each stage within a limited number of lives.
The game features four difficulty levels, with increasing speed for higher difficulties except for the final level which adds an additional red ghost.
