Retrovirus is a six degrees of freedom shooter which sends players into the depths a computer on a search and destroy mission against an invasive virus. Retrovirus is being created by Cadenza Interactive, the indie studio behind the popular tower defense game Sol Survivor. Players take command of an antivirus program, armed with the tools necessary to erase the virus’ very existence from the system. Movement and exploration are core to the gameplay, and players are encouraged to adapt to the demands of a world where free flight is the norm. Of course, the virus is armed to fight back, and first person shooter combat features heavily as players test their level of comfort with movement within the machine environment. Each player is able to customize their antivirus program with different plugins, allowing for a variety of approaches to a given situation.
