Under Siege is a 2011 real-time tactics video game developed by Portuguese company Seed Studios and published by Sony Computer Entertainment for the PlayStation 3.

On 23 August 2011, the game was released into the Asian market including Singapore, Thailand, Taiwan, Hong Kong, Malaysia, South Korea and Indonesia.

It’s engaging and, if the controls can be mastered and the bugs forgiven, a satisfying sampler of RTS thrills for the uninitiated, and a stamina test for anyone who thinks they’re hard enough.

Difficulty is spotty at best – even on the easiest levels it’s all too easy to accidentally wander into a massive enemy swarm because the fog of war is, frankly, too close to your units.
