Under Siege

The game achieved an aggregate rating of 69% on video game review site Metacritic, indicating "mixed or average" reviews that were representative of good value for money with good production values but significantly hampered in general appeal by difficulty spikes, and a high overall difficulty level. Edge gave the title a 7 out of 10, writing, "Under Siege may be a downloadable game, but it's certainly not throwaway. 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." Digitally Downloaded gave the game 4 stars out of 5 and stated, "There is some fine tuning that the game could have used, however. 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. And although the best effort has been done to get the controls down, it'll never manage to be as intuitive as mouse and keyboard for the strategy genre. But it's an impressive effort nonetheless, and a warm welcome back for the PSN. Given that everyone gets free PlayStation Plus subscriptions, take advantage of the fact this game is heavily discounted; it's well worth the budget asking price." Eurogamer gave it a 7/10, concluding that it was "A game that requires a degree of patience and tolerance before it truly clicks. If you have the required resolve, there's plenty to admire."

Under Siege has won the Grand Prize for the "Zon Multimedia Awards 2010" held in January 2011 at the "Museu do Oriente" in Lisbon, Portugal. It also won 1st prize for "Applications and Multimedia Contents".
