Worms Forts: Under Siege

Worms Forts: Under Siege blends castle-building with classic Worms combat

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

Instead of only focusing on hitting opponents with bazookas, grenades, and absurd weapons, you also need to build a base, defend your structures, and use your fort as a 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 test 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 silly weapons, but it also demands more patience because you constantly need to think about positioning, buildings, and access to stronger attacks.

Worms with fortresses, weapons, and more planning

In Worms Forts: Under Siege, you control a team of up to four worms fighting from their respective forts. GOG describes it as a 3D Worms game 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 hits. Here, you also need to build structures, expand your base, and make sure you can access better weapons and stronger attacks.

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

3D Worms with charm and slightly clunky controls

Worms Forts: Under Siege is in 3D, which makes it more lively visually 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 especially noticed that the game feels best once you accept it as something other than “just another Worms.” It’s not the fastest or most elegant entry in the series, but it has its own idea. You’re not only trying to hit the opponent—you’re also building your way to victory.

Thankfully, the humor is intact. The worms shout, panic, taunt each other, and get launched off the map exactly as you’d expect. The arsenal also has the familiar mix of standard and utterly 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 players, and that holds true here. Single-player works well to learn the systems, but the chaos and comedic moments shine when you’re playing against friends.

It’s especially fun when a well-placed building, a lucky shot, or a completely botched plan flips the entire match. Worms Forts: Under Siege isn’t always fair, but it’s often fun in that classic Worms way where everyone in the room is both laughing and groaning.

Don’t count on online activity as the main attraction today. The game is older, and local multiplayer, nostalgic revisits, and private matches with friends make the most sense.

Is Worms Forts: Under Siege still worth playing?

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

What it does have is a concept that still stands out: Worms with castle-building. That makes the game more tactical, a bit slower, and more idiosyncratic. For some, that’s a fresh twist. For others, the classic Worms games will feel much better.
