Do you remember the spaceship shooter game Blast Factor (available via PlayStation Network)? Well, replace the ships with cells, bacteria, and viruses and you could possibly get Kuju Entertainment's Nucleus.

Players will take control of a remote unit that can be used to shoot bacteria and viruses. Fire power comes in the form of protein bombs, but you have to collect enough protein ammo from cells. There's also a tractor beam that players can use to move the cells around and cluster them. The bigger the cell cluster, the more protein it will release.

Cells can also be used for protection, along with another type of cells called stiff cells. The stiff cells can be obtained from the enemy bacteria. There are three types of enemies: bacteria (the frontliners), viruses (faster and will break down into bacteria), and super viruses (fastest and baddest of them all). Different levels have different conditions. For example, players might be required to survive for four minutes and hold back barrages of enemies. Or have the player destroy all the enemies in four minutes.

Nucleus will be available for download on your PS3 by summer in Europe. There's no announcement as to a North American release but we'll keep you posted. In the meantime, check out the screenshots.
