Laser Squad Nemesis is a multiplayer turn-based tactics video game.
Players issue orders to a squad of soldiers or aliens. Each turn, the player gives orders to their troops, previews probable effects of those orders, and submits them to the LSN server via the web interface, or through email. Orders are resolved simultaneously after both players have submitted their orders, and the consequences of the round are sent back to both players. The result of the previous turn is viewed in a real time ten-second video, with pause, slow motion and rewind (multiple turns) options.
