Controls
Click walk there. The shield faces the boss on its own and pulls in what it can catch.
Right-drag build a wall along the drag (30 charge, up to eight). Walls eat bullets from any side and pay 1 charge each; the shield pays 4 but heats up.
F beam fires itself whenever it has 60 to spare above a 30 reserve (default), or only on Space, which fires at 60
P pause R restart
A hit costs 12 charge; only when you have none does it cost integrity, which never comes back. Heat drains the shield's absorbing: at 100 it drops for two and a half seconds. Streams announce their lane for 3.5 s and go for whichever wall earns you the most. Breakers crawl toward your walls and die to any beam that crosses them. Bastions rise between you and the boss and take the beam instead; walk out from behind them. After 4:00 the sky closes.

Why it's built this way

The first Bulwark had walls and a shield and a boss that read your style, and it was still a bullet hell: delay every input in a good run by fifty milliseconds and the run died. Everything that decided the fight happened in under a second, so nothing built on top of that loop could outweigh it.

This one moves the whole fight onto a slower clock. The boss doesn’t aim. It makes weather: a steady drizzle of bullets that take eight to twelve seconds to cross the arena, a sweep that wipes the sky and shows its line two seconds early, a stream that marks its lane for three and a half seconds before it flows. From phase two it sends breakers that crawl toward your walls, and raises bastions between itself and wherever you stand, three seconds after showing you where. You give it positions: a click is where to stand, a right-drag is where a wall goes. The shield faces the boss on its own, and the beam fires itself.

Charge is the only economy. The shield pays four per bullet it absorbs but heats up, and at full heat it drops for two and a half seconds. Walls pay one per bullet from any side, never heat, and cost thirty to build. A hit costs charge; only when you have none does it cost integrity, which never comes back. The beam costs sixty and takes eight percent of the boss. After four minutes the sky closes and the drizzle doubles every thirty seconds, so the structure has to be paying for the beam by then.

The slow way. Build a canopy above where you stand and let its shadow keep the drizzle off you. The boss’s plan is to grind it: streams go for whichever wall earns you the most, breakers try to demolish one, bastions take your beam until you walk out from behind them. Whether the structure holds under that is the whole game, and none of it is decided in under a second.

The fast way. Stand at the line under the boss, where the weather is thickest, and take it on the shield: four charge a bullet, no walls to buy. The heat bar is what you manage, and a stream you fail to step out of is twenty-five charge a hit.

Scripted runs of both, with every input delayed by five seconds: the canopy still kills the boss in every run, the rusher dies in every run. Without the delay the rusher is about a minute faster when it lives. That is the trade the page promises on the hub, and this is the first version of the game that actually makes it.
