The SentryBot first appears in TimeSplitters 2. They appear in the Story mode mission set at the Robot Factory, in which they are fairly slow but fairly hard to kill. Outside of Story mode, it makes several appearances in the Arcade League, as well as a single appearance in a Challenge and a bot set.
- On Robot Factory (Story), Night Shift and Demolition Derby the SentryBot has a unique death animation, falling backwards with its arms detaching at the same time. The arms twitch around on the ground before the body disappears.
- The SentryBot's character model seems to draw inspiration from the Super Battle Droid from the popular franchise, Star Wars.
