Overview

Siegecrawler is a physics-driven roguelike siege simulation from indie studio SMB Games, released on November 12, 2026. The premise is refreshingly blunt: walls exist to be broken. You draft fantasy soldiers onto a self-propelled siege engine and send the whole contraption crashing into castle fortifications. It sits comfortably in the strategy and auto battler space, wrapped in pixel art and roguelite structure.

Highlights

  • Seven unit classes — knights, archers, mages, lancers, clerics, berserkers and arbalests — can be placed freely across siege towers and a battering ram, so your formation effectively becomes your build.
  • Squad synergies such as "2 knights: melee HP +20%" stack with band bonuses that change depending on which deck you assign units to, rewarding careful layout over brute force.
  • Four commanders with distinct trade-offs shape each run, including the Ram King, who boosts ram damage and widens the Just Hit window but forbids ranged units entirely.

The commander system is where the roguelite tension really lives. The Arcane Legion hands you all five spells from turn one at the cost of half your deck, while the Elite Fe—another commander option—pushes a different kind of risk.

Because each run begins with a commander choice, the drafting phase feels like a commitment rather than a formality. Physics does the rest: collisions, impacts and collapsing walls are simulated rather than scripted, which gives every siege a slightly chaotic texture.

Who It's For

If you enjoy auto battlers where positioning and synergy math matter more than reflexes, or roguelites that ask you to rebuild a squad from scratch each attempt, this one is aimed squarely at you. Fans of pixel-art strategy with a playful physics twist should also feel at home. It is single-player only, supports save-anytime and Steam Cloud, and ships with English, Simplified Chinese and Japanese language support.
