High Seize is a turn-based pirate adventure and war game set in the 17th century Caribbean. The gameplay is similar to the Advance Wars series on the Gameboy Advance and Nintendo DS - a stream-lined strategy game that is divided to missions.

High Seize includes a single player story mode with cut-scenes and voice-over audio, and an upper level gameplay mode of sailing and character development.

The game supports 2-4 player multiplayer over a Bluetooth connection and in the Nokia N-Gage Arena via a GPRS connection. The multiplayer can also played on one device with the hotseat mode.
