Worms Forts: Under Siege

Worms Forts: Under Siege blends fortress-building with classic Worms warfare

Worms Forts: Under Siege is a turn-based strategy game where the familiar Worms trade open battlefields for fortified bases, castles, and more tactical building.

Instead of only focusing on hitting your opponent with bazookas, grenades, and absurd weapons, you also need to build a base, defend your structures, and use your fort as the launchpad for attacks. That gives the game a slightly different rhythm than the most popular Worms titles, and that’s both the strength and the weakness of Worms Forts: Under Siege.

In our testing on Windows 11 via GOG, the game felt like an offbeat branch of the Worms series. It has the humor, the mischievous little worms, and the goofy weapons, but it also demands more patience because you’re constantly thinking about placement, buildings, and access to stronger attacks.

Worms with fortresses, weapons, and more planning

In Worms Forts: Under Siege, you command a team of up to four worms fighting from their own forts. GOG describes it as a 3D Worms title where you can both defend from your castles and attack the enemy in classic Worms fashion.

It sounds simple, but it actually changes a lot. In many Worms games, it’s all about angles, wind, timing, and clean weapon hits. Here, you also need to build structures, expand your base, and make sure you can unlock better weapons and stronger attacks.

That gives the game a fun fort-vs.-fort vibe. When it clicks, it feels almost like a mix of Worms, light base-building, and chaotic party-game action. When it doesn’t, it can be a bit slower and clunkier than the classic 2D entries.

3D Worms with charm and slightly clunky controls

Worms Forts: Under Siege is fully 3D, which makes it more visually lively but also less precise than the classic 2D versions. The camera and movement take some getting used to—especially if you’re coming straight from Worms Armageddon or Worms World Party.

We found it plays best once you accept it as something other than “just another Worms.” It’s not the fastest or most elegant entry, but it has its own idea. You’re not only landing shots—you’re building your way to victory.

Thankfully, the humor is intact. The worms shout, panic, taunt each other, and get blasted off the map exactly as you’d expect. The arsenal also delivers the familiar mix of standard and downright goofy attacks, including medieval-inspired weapons that fit the fort theme.

Multiplayer is still the best way to play

Worms has always been best with other people, and that’s true here as well. Single-player is fine for learning the systems, but the chaos and comedic moments shine when you’re playing with friends.

It’s especially fun when a well-placed structure, a lucky shot, or a totally botched plan swings the entire match. Worms Forts: Under Siege isn’t always fair, but it’s often hilarious in that classic Worms way where everyone in the room is laughing and grumbling at the same time.

Don’t expect online activity to be the main draw today. It’s an older game, and local multiplayer, nostalgic throwbacks, and private matches with friends make the most sense.

Is Worms Forts: Under Siege still worth playing?

Worms Forts: Under Siege is worth a try if you already like the Worms series and want to experience one of its more experimental outings. It’s not the best place to start for newcomers, and it isn’t the series’ most polished game.

But it does have an idea that still stands out: Worms with fortress-building. That makes the game more tactical, a bit slower, and more distinctive. For some, it’ll feel like a fresh twist; for others, the classic Worms games will feel much better.
