Зомби в доме: Заражение – Учёный ("Zadventure: Scientist") is an expansion of the Zadventure game. It allows up to five players to play, with a new character called Scientist who has a portal gun. Now there are no obstacles for you. Just use the portal near the wall to get through where there was none before. True, it only works twice, but that's better than nothing.
Also, this expansion introduces a new Tamer mode, where one player initially plays as the Tamer against the others. Each turn, he summons a new zombie from the grave and controls all the zombies on the board. However, at some point, he can summon a zombie tiger that is completely immortal. The player character's main task does not change, but the Tamer must use their zombies to capture four special artifacts on the board in order to win.
