Worms Forts: Under Siege for Windows

A fresh layer of strategy for chaotic combat

Worms Forts: Under Siege keeps the series’ cartoonish humor and explosive antics, but it adds a meaningful building mechanic that changes how battles play out. Rather than only lining up shots across the map, players design and protect multi-structure bases while directing their worm squads. The mix of base construction and turn-based skirmishing creates additional tactical choices without losing the franchise’s signature silliness.

Designing and linking your stronghold

The Stronghold serves as the core of every base, and new structures must be physically connected to it. Placement matters: how you chain buildings together affects which facilities you can use and how easy they are to defend.

Key structure types (examples and order vary from other descriptions):

• Citadel — the top-tier construct, granting access to elite systems and powerful armaments
• Keep — a mid-level building that opens upgraded gear and defensive bonuses
• Tower — basic outposts that provide early weapons and functions

Other functional buildings, like Science Labs for tech unlocks and Hospitals for healing, slot into your layout and change the pace of play. Because links back to the Stronghold are required, expansion forces careful planning rather than random placement.

How weapons and upgrades are tied to construction

Weapon availability is determined by the buildings you control. Lower-level installations let you use standard Worms fare, while superior structures enable catastrophic options that can swing entire matches.

Examples of weapon tiers and special systems:

• The Wonder — the ultimate prize that delivers the most devastating effects
• Large siege devices — powerful, structure-dependent weapons that reshape the battlefield
• Conventional arms — familiar explosives and gadgets available from basic buildings

This progression discourages pure brute-force play and encourages players to weigh expansion and preservation against aggressive assaults.

Campaign format and challenge curve

The solo campaign comprises 20 missions arranged into four thematic eras, each containing five scenarios. Environments, enemy behavior, and available constructions evolve by era, forcing players to adapt tactics as new tools appear.

• Each era introduces fresh mechanics and layout challenges.
• Difficulty ramps up, blending base management with turn-based survival.
• The campaign rewards learning how to balance fortress growth with keeping worms alive.

Because of these layered systems, the campaign feels deeper than many previous Worms entries, though there is a noticeable learning curve for newcomers.

Competitive play and staying power

Beyond single-player, the game supports matches against others via LAN and local hotseat, letting friends test fort designs and strategies against human unpredictability.

Multiplayer highlights:

• LAN play for networked battles with reduced input lag and larger groups
• Hotseat mode for classic, couch-based turn-taking and quick sessions
• Replays and varied fort layouts that encourage repeated matches

Between structural strategies, weapon progression tied to buildings, and the franchise’s enduring comedic tone, the game offers substantial replay value.

Bottom line

Worms Forts: Under Siege updates the series by blending its familiar chaos with a fortress-building layer that genuinely impacts strategy. With a 20-mission campaign across four eras, a weapon progression tied to structural growth, and both local and networked multiplayer, it provides a distinct, tactical twist on the Worms formula.
