Strengths and limitations

In the grim darkness of the 41st millennium, the alien (or "xenos") is a constant threat. While other Imperial forces fight against heretics and daemons, the Deathwatch, the chamber militant of the Ordo Xenos, is specifically tasked with the eradication of extraterrestrial life. The Deathwatch core rulebook established players as members of this elite, but a key piece was missing: a dedicated "monster manual." Mark of the Xenos was published in 2011 by Fantasy Flight Games (FFG) to fill this gap. Serving as a crucial supplement, it provides a massive catalog of alien species, heretics, and chaotic entities that the Deathwatch faces within the Jericho Reach.
