Which Nemesis expansion after the base game?

The game

Already own Nemesis? The expansions split three ways: new Intruder races for the ship, and two standalone sequels that each start their own expansion line.

1-5 players. Carnomorphs and Void Seeders need the original Nemesis. Chytrids needs Lockdown. The newest wave needs Retaliation.

Lockdown and Retaliation are games, not expansions. Lockdown moves to a Mars base with Night Stalkers. Retaliation sends in marines on a modular ship. Neither needs the original box.

Chytrids is the bridge box. It is a Lockdown expansion that also lets Carnomorphs and Void Seeders invade Lockdown. Retaliation boxes do not work backwards.

Availability moves fast. Nemesis printings sell out and return. If a box below is between printings, the order still holds when it comes back.

FAQ

Which Nemesis expansion first?

Carnomorphs for mutations and a butcher at the table, Void Seeders for madness. Both replace the Intruders of the base game.

Is Lockdown an expansion?

No. Lockdown is a standalone game, expanded by Chytrids.

What does Retaliation need?

Nothing else: it is the third standalone game. Its expansions (Sanguivores, Xyrians, Support Squad, Untold Stories 4 and the stretch-goal box) need Retaliation.
