Protozoa screen 1

You start off as a single cell organism, the objective of the game is to become multi-cellular by consuming other small organisms that swim around the screen. Points are scored for every organism consumed: 10 points for a single cell, 25 points for a double cell, 50 points for a triple cell, and a point is scored for every cell gained at game over. The number of enemy organisms for each game can be selected from 1 to 4, if you run into an enemy it's game over, be careful not to run into yourself or it's also game over.

Protozoa is a game created by Ruckage, developed with Fenix for the GP2X console. The game was initially inspired by the flash game flOw (but the two games have virtually nothing in common) and a mini-game that featured in Timesplitters 2.

Protozoa screen 2

This release comprises of the GP2X version of Protozoa along with DCEvolution's version of Chui's Fenix SDL Loader (FSL) from November 2004, edited to exclude the Fenix splash screen and jingle, so the game loads directly.

The Dreamcast Fenix port does not have support for music in the OGG format, the soundtrack for Protozoa (a tune with a total running time of fifty six seconds which loops during game play) has been excluded from this Dreamcast version. Protozoa has also been edited so all the available control options for the GP2X are now available on Dreamcast. Due to the alterations made to the game for a Dreamcast release, a download for the original GP2X version has been made available (the GP2X Fenix runtime is also included in the download).
