    Aftermath

    Buy this first

    Reddit says most owners find it worth it for the characters and trait cards. Several say the Epilogue mode rarely gets played and recommend the Research Mission variant.

    Needs: Needs the Nemesis base game or Nemesis: Lockdown.

    Adds: 5 new characters, character trait cards, new rooms and turrets, a shuttle board, and Epilogue and Research Mission modes that extend or reshape the game.

    Fixes: Gives the base game more character variety and asymmetry; the Research Mission variant folds everything into one longer game.

    Carnomorphs

    Worth it

    Reddit owners find it a distinct feel from the base aliens but one says it made their game easy; it is seen as optional variety rather than essential.

    Needs: Just the base game

    Adds: A second alien race (Larvae, Metagorgers, Shamblers, Fleshbeasts and a Butcher), mutation cards and burnable corpses; players can be infected and mutate.

    Fixes: Adds a different threat to the intruders and changes how infected players behave.

    Void Seeders

    Worth it

    Reddit owners say Void Seeders can be an even harder challenge than the base game and one prefers it over Carnomorphs; it is treated as optional variety.

    Needs: Needs the Nemesis base game or Nemesis: Lockdown.

    Adds: A third alien race (Voidlurkers, Whisperers, Stalker, Despoiler) with insanity and contamination cards and multiple nests.

    Fixes: Replaces the intruder threat with one that manipulates players mentally.
