Our take on Siege Island

The setting and enemy variety receive prominent attention, but the current version uses one island grid with fixed castle positions and cell counts. More grids, wall pieces, bosses, and a new setting are identified as planned Early Access work rather than current content.

What is Siege Island?

Siege Island is a 3D action-puzzle game based on the arcade game Rampart.

Players defend several castles against waves of enemies arriving by sea and air. In each building phase, Tetris-like wall sections are used to surround castles. Secured areas allow cannons and ballistas to be placed before the next attack. A castle is lost, along with its weapons, if it is not fully enclosed when construction ends. Defeating enemies earns gold and brilliants for upgrades in Defense, Attack, and Magic. Players choose a Human, Dwarf, or Elf, each with distinct attributes and one race-specific spell. The current version includes four settings, three enemy types, one boss ship, one island grid, progress saving, and six listed languages.
