"Resistance is a series of first-person shooter video games developed by Insomniac Games and published by Sony Computer Entertainment for the PlayStation 3 and PlayStation Portable game consoles. The series takes places in an alternate history around the year 1950 in which an alien species known as the Chimera have taken over all of Russia and continue to expand to Europe and the United States, converting humans into super-powered soldiers. The player takes the role of one of the remaining human armed forces as they fight against the Chimera invasion.
The series is noted for its use of both conventional and futuristic weaponry, reflecting Insomniac's previous work on the Ratchet & Clank series."
