Space Marine Operations: New Threats and Missions

February 2026·pp. 22–29

THE SHORT VERSION

The cooperative mini-game gains two Tyranid enemies, revised spawning tables, two missions adapted from Space Marine 2 and alternative perks for all six Marine classes. These are extensions to the previously published core game, using Boarding Actions terrain and existing miniature collections rather than the normal army-scale rules.

Deadly Encounters: Tomb Worlds

Optional narrative rules turn Killzone: Tomb World into an unpredictable Necron complex. Unexplored rooms acquire persistent environmental effects when first entered or opened, while objectives reveal their own mechanisms when first contested or controlled. Separate instructions adapt the same discoveries to head-to-head games or solo and cooperative missions without letting non-player operatives prematurely reveal the surprises.

Tomb World Room Features

Collapsed ceilings, darkness, corrosive leaks and energy ruptures make the safest route through a tomb difficult to predict. Other results interfere with specialised actions, alter activation order or exchange movement speed for melee strength. The room table remains relevant after discovery, rewarding players who reconsider positioning rather than merely treating an opened door as cleared terrain.

Tomb World Objective Features

Objective devices range from defensive shields and dangerous Tesla equipment to teleportation links, command resources and temporal manipulation. Others improve close-combat lethality, offer a last chance at survival or let an operative overcharge a weapon. Because a carried objective retains its feature, the rules can transform both a location and the operative transporting it.
