Unit 13 is a third-person shooter video game developed by Zipper Interactive and published by Sony Computer Entertainment for the PlayStation Vita.

All missions can be played co-operatively, and each mission features an unlockable "Dynamic" Mode, which changes objectives and objective locations, enemy weapons and locations, to random values and points in the environment.

However, Dynamic mode does not support leaderboard ranking, as the mission has random insertions and objectives.

The demo version allows for six playable characters, Commando, Technician, Pointman, Gunner, Infiltrator, and Marksman.

All characters may progress up to level 4 by completing the single mission well and gaining experience for performance.
