Its major features are an updated version of the Xngine allowing for play in the sharper 640x480 resolution (and the ability to update Future Shock to the same), a new single-player campaign, and a new multiplayer deathmatch component. Originally developed as an expansion pack to Terminator: Future Shock, SkyNET eventually became its own standalone product. SkyNET is Bethesda's last game based on the Terminator franchise.
