Space Marine 2 gets discount, free trial, and Siege Mode overhaul

Space Marine 2 is holding onto multiplayer momentum in a way few big-budget shooters manage, and Saber Interactive is now leaning into that strength with a discount, a free trial, and a major overhaul to Siege Mode. The game has recently been clearing more than 21,000 concurrent players in a day, a number that puts it ahead of newer multiplayer releases like Dune: Awakening and keeps it looking lively in a crowded field.

The timing matters because Space Marine 2 did not arrive as a traditional live-service platform. It launched on September 9, 2024, as a relatively straightforward action sequel, then steadily grew a cooperative identity through new missions, monsters, classes, and modes. By April 2026, Focus Entertainment said the game had reached 12 million players and that live support had been extended into a third year, a signal that the post-launch plan had become central to the game’s identity rather than an afterthought.

That support took another step forward with the Purgation Update, Patch 13, which went live on May 21, 2026. The update is free for PlayStation 5, Xbox Series X|S, and PC players, and it adds a new PvE Operation called Purgation set in the Kadaku swamps, a Battle Simulator practice arena, new loadouts and perk swapping during a session, and the Iron Hands Chapter Pack for Season Pass 2 owners. Focus also said the patch brought a major Siege Mode revamp, plus fresh bosses, additional objectives, and a new Blessings and Atonements system for Siege 2.0.

That is the sharpest sign yet that Saber and Focus understand the game’s incentives. The first Siege mode, added in Patch 8.0, centered on endless enemy waves and reinforcements when teams were overwhelmed. Siege 2.0 turns that idea into a fuller retention loop, one built to keep squads coming back for harder runs, more variety, and a reason to relearn the mode. Add in the new discount and free trial, and the message is clear: lower the barrier for new players, then give existing players a deeper reason to stay.

Space Marine 2 is now operating less like a one-and-done sequel and more like a stubborn multiplayer holdout, one that is still widening its funnel while keeping its core co-op crowd busy. In a year when other shooters have struggled to convert attention into staying power, that is the real story behind the patch notes.
