If you’re craving for more ways to purge xenos in Warhammer 40,000: Space Marine II, today’s your lucky day. Focus Entertainment and Saber Interactive just announced the Siege Update. It’s a brand new endless wave defense mode, and the good news is that it’s completely free for everyone.

The free update adds a brand-new gameplay option and revamps many elements of the current game.

The free update for Warhammer 40,000: Space Marine 2 is now available for players on PlayStation 5, Xbox Series X|S and PC via Steam, alongside two cosmetic DLC packs for Season Pass holders. Whether you’re a veteran battle-brother or considering to fight for the emperor of mankind, this update is the perfect excuse to don a power armor.

What’s New in the Siege Update?

New Game Mode: Siege

The main highlight of the update is the new Siege Mode, a three-player PvE experience that will test how long your squad of Space Marines can hold an Imperial Fortress on the planet Kadaku. Unlike the Operations missions with clear objectives, Siege throws your squad against endless waves of enemies in a true last-stand scenario.

Hordes of enemies alternate every 5 waves, meaning that if your squad faced off against the Tyranids in waves 1-5, the next 5 waves would pit you and your two other teammates against the Tzeentch-worshippers, the Thousand Sons. As you play through the waves, you can gather Requisition Points which you’ll use as currency at Acquisition Terminals to purchase upgrades, reinforcements and other consumables that can be invaluable against the next waves of enemies. One of the things that caught my eye in this trailer is that it’s possible to call in a whole platoon of Cadian troopers as well as a Dreadnought even though it’s hefty at 1500 points. Gameplay-wise, though, if you’re going to ask me, I’d prefer to fight against the Tyranids and Chaos Marines in an alternate fashion with a few bosses in between, just to give the game a bit more shock and excitement.

New Chapter Cosmetics

Alongside the free Siege mode, Patch 8 also delivers two new cosmetic DLC packs for Season Pass holders. Here’s a list of cosmetics that you can get for the White Scars and Blood Angels Space Marine Chapters:

Chapter	Inclusions
White Scars	Successor Chapters Cosmetics Pack
	Champion skin for the Assault Class
	Stalker Bolt Rifle Weapon Skin
	Combat Knife Weapon Skin
	Occulus Bolt Carbine Weapon Skin
Blood Angels	Successor Chapters Cosmetics Pack

Why You Should Jump In Now

Warhammer 40,000 Space Marine 2 Siege Update Announcement

If you’ve held off on getting Space Marine 2, this might be a good time to check it out. There’s already a lot of content available from previous updates and who wouldn’t want to play as an Astartes against hordes of xenos and traitor marines?

The game is also accessible with cross-play, but might require patience for matchmaking since the number of the concurrent players on steam is dipping as of the moment. That said, I believe that the Siege Mode is a good step in the right direction and this update might be interesting enough to hook in new players and get older players invested once more.

The Siege update for Warhammer 40,000: Space Marine 2 is available now on PlayStation 5, Xbox Series X|S and PC. The update is free for all players who owned the game, with cosmetic DLCs exclusive to Season Pass Holders.
