Build by day. Survive the skeleton siege by night.

YAARRGH! Battle Island! is a co-op pirate PvE survival crafting roguelite where every day is preparation for the siege to come.

Explore procedurally generated islands, gather and mine resources, process materials through interconnected crafting chains, build a fortified pirate stronghold, and prepare your crew before nightfall.

When darkness comes, escalating skeleton hordes attack everything you built.

Gather. Mine. Craft. Build. Defend. Survive.

By Day: Gather, Craft & Prepare

Explore the island for resources, loot, food, and buried treasure.

Chop trees, mine stone and iron, hunt for materials, dig for valuables, and bring everything back to your base.

Raw resources can be processed into useful crafting materials:

* Turn trees into "trunks and logs"

* Process timber into "boards, planks, posts, palings, and firewood"

* Smelt "iron" into crafting components

* Process "stone" into building materials

* Cure hides into "leather"

* Produce "rope"

* Gather food and water for cooking

Use specialised workstations such as the "Saw Horse, Saw Bench, Furnace, Leatherworking Bench, and Cooking Pot" to expand what your crew can produce.

Your resources are not just inventory.

They become the walls, weapons, supplies, and structures that keep you alive.

🔨 Build Your Pirate Stronghold

Turn your crafted materials into a fortress before the skeletons arrive.

Build and expand:

* Palisades

* Fortification walls

* Gates and gatehouses

* Defensive towers

* Stairs and ramps

* Ladders and platforms

* Shelters and gazebos

* Storage structures

* Workstations

* Cooking stations

* Cannons

* Traps and defensive equipment

Choose where to build, reinforce weak points, create choke points, and prepare your defenses for the coming siege.

What you build during the day determines how well you survive the night.

🔨 Survival Crafting

Crafting is at the heart of preparing your island.

Instead of simply collecting materials, your crew processes resources through multiple stages before turning them into useful equipment, structures, food, and defenses.

A tree might become a trunk.

A trunk becomes logs.

Logs can become boards, planks, posts, palings, or firewood.

Those materials can then become walls, towers, gates, shelters, workstations, and other structures that help your crew survive.

Other crafting paths include metalworking, stone processing, leather and rope production, cooking, fortification construction, and shipbuilding.

As your crafting network expands, so do your options for surviving the increasingly dangerous nights.

SURVIVAL TAKES MORE THAN WALLS

Keep your pirate alive as the pressure increases.

Catch fish, prepare ingredients, collect water, and fuel your cooking pot to create fish stew that restores health. Build the infrastructure needed to keep your crew supplied while preparing for the next attack.

Your time during the day is limited. Gather too little, craft the wrong materials, or leave your defenses unfinished, and night will expose every weakness.

SURVIVE THE SKELETON SIEGE

When night falls, the island fights back.

Skeleton hordes assault your fortifications in increasingly dangerous waves. Defend breaches, fight enemies directly, man your defenses, and keep the stronghold standing until morning.

As the nights progress, expect larger attacks, stronger enemies, and increasingly dangerous siege pressure.

If your defenses fail, the skeletons come for you next.

⛏️ Dig, Mine & Unearth Resources

Not every valuable resource is sitting on the surface.

Explore each island for places to dig and mine, uncovering materials your crew needs to expand its crafting network and strengthen its defenses.

Mine stone and iron for construction and crafting, then process those raw resources into useful materials for stronger structures, equipment, and fortifications.

Digging can also lead to buried treasure and valuable loot, giving your crew another reason to explore beyond the safety of the base.

The challenge is deciding how far you are willing to venture before nightfall.

Do you keep mining for the materials needed to finish another defensive wall? Search for one more buried treasure? Or return to the stronghold before the skeletons arrive?

Every expedition underground or away from camp costs precious daylight—and when the sun goes down, unfinished defenses can become a serious problem.

Explore. Dig. Mine. Bring it home. Build something that helps you survive the night.

BUILD AND SURVIVE TOGETHER

Play solo or form a pirate crew with friends.

Divide the work during daylight: one player can gather timber while another processes materials, cooks supplies, or expands the fortifications.

When night comes, regroup and defend together.

Fight skeletons in fast-paced combat, protect key structures, repair damaged defenses, reinforce weak points, revive fallen crewmates, and prevent the enemy from overwhelming your stronghold.

The longer you survive, the more dangerous the attacks become.

What looked like an impressive fortress during the day can quickly become a desperate last line of defense after nightfall.

Cover breaches. Protect your workstations. Fight from the walls. Keep your crew alive.

The more dangerous the island becomes, the more teamwork matters.

🏝️ Procedurally Generate Islands

Every run takes place on a procedurally generated island with different terrain, resources, treasures, and defensive opportunities.

Explore your surroundings, decide where to establish your stronghold, and adapt your gathering, crafting, and building strategy to the island you are given.

No two runs play the same way.

Roguelite Progression

Grow stronger from run to run with new upgrades, stronger builds, and evolving strategies.

• Randomized upgrade paths

• Unlockable abilities

• Powerful run-defining synergies

• Permanent progression between attempts

Push further with every run.

Gather. Mine. Craft. Build. Defend. Survive.

YAARRGH! Battle Island! Blends survival, crafting, mining, base building, and roguelite progression into a flexible pirate create-your-own-adventure, where every run gives you new ways to prepare. Explore the island, dig and mine for valuable resources, process raw materials, craft gear and supplies, and build the kind of fortified stronghold your crew needs to survive. Discover new upgrade paths, experiment with different crafting and building strategies, and adapt your defenses as the skeleton sieges grow more dangerous.
