Bulwark: Onslaught

Hold the line against the horde.

Urgrom Skullcrusher’s horde is marching south. Goblins, orcs, ogres and wolf riders want to burn every farm, village and castle in the North — and only your party of three stands in their way. Defend the well through seven waves and a boss. If it falls, it’s over.

Three heroes, one horde

Team up with two friends in real time — or bring AI companions. Paladin tanks, mage burns, cleric keeps everyone standing.

20

Roll at the altar

After every wave you roll a D20. The higher the roll, the rarer the cards — pick one and reshape your build mid-fight.

Bosses that fight back

Charges, axe whirls, stone skin, war drums. Read the red zones, break the runestones, live to brag about it.

Loot worth fighting over

Rarities, sets and runewords. Skill trees with three schools. Your renown rises with every win — and so does the threat.

Try it

Roll the altar die

Tap the D20. 11+ rare, 17+ epic, a natural 20 is legendary. These are real upgrade cards from the game.

Bindrune Duels

Your finger is the wand.

Two wizards. One screen. No buttons. You cast by drawing runes — the cleaner and faster your stroke, the harder it hits. Every spell telegraphs itself, so the duel is a conversation: read your opponent, raise the right shield, and punish the miss.

Cast a spell

Draw one of the eight starter runes in one stroke. Quality decides power: under 55% it fizzles, a perfect stroke hits for ×1.35.

    Drawing is skill

    No menus, no cooldown buttons. The whole screen is your canvas — skill lives in your hand.

    Reading is countering

    Aura, gesture, focus: every cast reveals itself in three stages. Guess early or wait and be sure.

    Combos in one gesture

    Two runes in a single stroke make a dual-element spell no single shield can stop. Lava. Plasma Strike. Frostbrand.

    Knowledge is power

    Research spells, brew charms and weave robes in your sanctum. Recipes are hidden — but deterministic. Crack them.

      The studio

      Small studio.
      Big trouble.

      trollr Studios is an independent game studio from Germany. We make the mobile games we want to play ourselves: short sessions, real skill, no ads, no nonsense.

      Everything is built in Godot, tuned with data and play-tested until our thumbs hurt.
