ESWAT: City Under Siege

ESWAT: City Under Siege, or simply E-SWAT, is a game released in 1990 for the Mega Drive. The game is known for its gameplay, but has been deemed "repetitive."

Interestingly, the game was based on an already existing arcade game. Backbone Entertainment also pitched an idea for another game, but it was scrapped.

Plot
A mysterious and high-tech organization, named "E.Y.E.", quickly threatens to take over the entire city and, after being promoted at the end of the second level, Duke Oda is given power armor called the "ICE Combat Suit". With this suit the player can use new and more lethal weapons; "Super Shot", a plasma rifle, rockets, and a devastating fire attack if he finds them. The player also has access to a jet pack with limited fuel that replenishes over time. Finally, this armor will allow the player to take more damage before being defeated. Unfortunately, because the suit makes him larger, it is harder for him to dodge enemy attacks. The final boss of the game, the leader of E.Y.E., is revealed to be a robot with artificial intelligence that is attempting to replicate its own ICE Combat Suits to take over Liberty, but is ultimately defeated.

Gameplay
The game is a sidescrolling platformer similar to Shinobi. It is set in the near future, where the player controls a blonde haired police officer named Duke Oda (デューク・オダ) who, over a series of levels, before receiving an armored power suit. At first, as a rookie member of the Cyber Police force in the city of Liberty, the player has to clean the streets of an overwhelming crime wave and terminate the most wanted criminals. In the first and second levels of the game, the completely human Duke Oda can only utilize a single shot weapon and can only survive one hit, similar to Contra. A second hit will kill him.

Reception
The game was mainly well-received and praised for its gameplay, but the graphics have been criticized. It also has been deemed "repetitive" by critiques.

Although, people have also deemed it as "highly addictive" and challenging.
