After being approved by Sony last week, Under Siege has finally been given a solid release date. Seed Studios game producer Filipe Pina made the official announcement via the PS Blog earlier today, confirming the PSN release for May 3rd.

Under Siege is a real-time strategy game exclusively for the PlayStation Network, featuring a full single-player campaign, multiplayer co-op/split-screen, and full fledged map editor. The title also supports 1080p HD visuals, Dolby Digital 5.1 audio, audio and video chat, video recording, screenshot capture, and custom soundtracks.

For $19.99, Under Siege provides quite a bit, mainly supporting the Dualshock 3 controller as a key aspect (while adding Move support) and then having a creative and in-depth map editor that establishes a high bar in replay value. So remember the date, May 3.
