Islands

Explore Into the Breach islands: Archive, R.S.T., Pinnacle, Detritus, and the Volcanic Hive. Learn about environments and regions.

Into the Breach involves saving four Corporate Islands in the Corporate Archipelago and destroying the Volcanic Hive of the Vek. Each Corporate Island has a primary environment and is run by a specific Corporation. Island names are informal and can refer to their environment, corporation, or other descriptors.

The islands are:

• Archive Island (also Museum Island or Temperate Island) of Archive, Inc.
• R.S.T. Island (also Desert Island) of R.S.T. Corporation or Rust Corporation
• Pinnacle Island (also Frozen Island or Ice Island) of Pinnacle Robotics
• Detritus Island (also Industrial Island, Factory Island, or Acid Island) of Detritus Disposal
• Volcanic Hive, which becomes available after securing at least two Corporate Islands.

The Volcanic Hive has two battlefields on two different levels instead of regions. The Corporate Islands all have 8 regions. Region names differ in each timeline, and the Corporate HQ can be in any region, but the physical layout and region boundaries remain constant. You have enough time to perform Missions in four of the regions before defending the Corporate HQ; the remaining three regions are overrun by the Vek. The maps show one possible configuration for each island, with red regions being the Corporate HQ, green regions secured from the Vek, and blue regions overrun by the Vek. The Corporate HQ can be in any region, and these maps illustrate region layout, not content.

Each mission area in a region takes place on an 8x8 grid divided into tiles. All mission areas have ground tiles. Common tiles include Mountains, Water, Buildings, and Chasms. The Temperate and Frozen Islands have Forest tiles that can catch fire. The Desert Island has Sand tiles that fill with Smoke. Ice tiles appear on all islands except the Desert Island. The Industrial Island features ACID tiles, which are corrosive water that doubles weapon damage. The Volcanic Hive has Lava tiles that act like water tiles and set surviving units on Fire.
