The game is hosted on Sony Pictures’ official Salvation site and invites players to engage in battle as either Skynet's fearsome Terminator machines or the Resistance. There are multiple different battles occurring at any given time that visitors can pick from and participate in. You can enter as a guest or a registered user, the latter of which allows you to record points on a leaderboard. Once you've entered a specific game, you can click on characters from whichever side you’re on to activate them. You can then use your arrow keys to move around and the 1 and 2 keys to fire off a main attack and a special attack, respectively.
The left side of the interface features a tiny map that tracks your positioning and a chat box to communicate with the other players, while on the right there’s a display indicating your team’s health levels. Your ultimate goal is to kill off all the opposition or destroy their vital item, which depending on your character is the Skynet Satellite Receiver or the Resistance's helicopter.
