Nucleus (also known as Bacterius on the Japanese PSN) is a puzzle-based shooting game with a dual stick control system similar to Robotron: 2084. Players are tasked with ridding a host body of a virus infestation, moving through the body's three main biological systems, the digestive system, the circulatory system, and finally the nervous system, culminating in a final battle in the brain.

The basic game consists of shooting bacteria or progressively larger and larger viruses, which break down into smaller viruses when shot, or if left alone combine themselves into ever larger viruses. Each level also has a number of cells which clump together and interact in a physical manner, the players can move them around and manipulate them with a traction beam to construct barriers to hide behind or to block of parts of the dynamically changing levels.

Ultimately the game is a high-score attack. Each level is tuned so that certain advanced techniques have to be used in order to achieve the higher scores, with correspondingly higher grades given to mark progress. These techniques are all discoverable to begin with, but they aren't explained in the initial instruction set. Later levels force you to learn these techniques, hints for failed attempts point the way, and by going back to earlier levels you can more easily achieve the higher level grades.

The game can be played in a 2-player co-operative mode offering more ways to build and manipulate cell structures or to distract and defeat the Nucleus enemies.
