Phage Wars 2

In Phage Wars 2, the player is a lab tech whose goal is to create the most powerful virus ever. This is accomplished by playing through the 32 stages (called 'experiments') and adding the gene proteins you discover to your virus in order to improve its strength, speed, defense, agility, and ability to reproduce.

Each of the 32 experiments contains a number of cells and enemy viruses. The player can choose to infect cells or attack cells which are already infected by an enemy virus in order to take them over. Once a cell is infected, the virus inside begins to reproduce, so the player can then attack other cells. The stage is won when no enemy viruses remain. A new gene protein is discovered after beating each stage for the first time.

Between experiments, the player has the opportunity to add the gene proteins to his virus. The proteins have varying effects, and can increase some statistics while decreasing others. Additionally, each protein takes up a certain amount of space in the virus's genetic code, so the player must choose between them to create the strongest virus.
