A new patch for Warhammer 40,000: Space Marine 2 introduces an exciting horde mode called Siege. In this mode, players can engage in wave-based combat against Tyranids and Chaos Marines, while also facing boss battles every fifth wave. The gameplay features three different sectors where players can complete side missions and upgrade their gear between rounds.

Players can also call in reinforcements and even tap into resources to summon a powerful Dreadnought. Surviving 15 waves will unlock an endless mode that ramps up the challenge even further, reducing available resources and prep times.

Notably, the Bulwark class gains access to a Thunder Hammer, as the developers felt it would add significant fun to combat.

The patch is set to be a free update for all players, bringing new cosmetics along with the horde mode itself. However, it also introduces a set of paid-for cosmetics that players can purchase.
