E-SWAT - City Under Siege — About this game
The Master System E-SWAT begins with an ordinary officer facing a city overrun by Balzar's gang. Clearing the first round brings promotion and an armoured suit, opening access to special items in later battles. Regular shots consume ammunition, while the timer keeps pressure on your advance through streets, rooftops and hostile buildings. Enemies attack from above as well as from either side, so crouching, jumping and angled fire all matter. Collect bullet supplies and save special attacks for dangerous groups rather than reaching the next boss with empty weapons.
