Nemesis Lockdown is first stand alone expansion to Nemesis. During the game, players will be taken to totally new location - a secret base on Mars, represented by a multi level board. Lockdown will keep the highly cinematic, semi-co-op experience of the original game, while introducing a lot of new, fresh mechanics.

During the tense gameplay you and your fellow playerswill gather items, explore different rooms and use your actions, craft, run and fight other species. During all that, every player will try to complete their secret objective, that will grant them victory... Sometimes at the expense of others.

Some of the new mechanics are:

- Multi-level base with stairs and elevators

- Advance computer actions

- Contingency procedure

- New characters and alien race
