Nemesis: Lockdown is a sci-fi role-playing adventure with turn-based combat based on the Nemesis board game. The base on Mars was blocked due to an alien attack. You are one of the few who remain inside. The main goal is to complete the assigned task, in which you will test your survival skills. The gameplay of the game is done in turn-based mode. To perform certain actions you have to use special cards. During survival, the character's task is not to destroy as many alien enemies as possible, but to outsmart them using his wits and careful planning of actions. The use of weapons, according to the developer, is a last resort.
