The Steel Giant

 is an enemy in Swamp Attack.

Physical appearance
The Steel Giant is a massive Olive-Drab tank with a white roof, topped off by the metallic base of an Evil Blaster. Two exhaust pipes can be seen in the back. The turret comes with a short main gun and a glass visor. On the sides there are grey and green metal wheels encased by its treads. Small panels and buttons located to the sides of a turret form a sharp contrast with its surroundings.

Gameplay
The Steel Giant is extremely dangerous. Its attacks inflict moderate damage but are spewed away at a high rate, demolishing the player's house in just a minute. The icing on the cake is its extreme durability and total immunity to paralysis, with nothing stopping its rampant barrage.

A fully-upgraded Flamethrower or Crossbow can be used to significantly damage the tank and any accompanying rivals, whist a Blob Thrower can be used to chip it down. Most explosives save for Beehives should not be relied on since they do very little to this hulking beast.

Trivia

 * The Steel Giant might be a reference to the Iron Giant in his titular film.
 * Both are massive, metallic machines, seemingly relevant to the Soviet Union and capable of mass devastation.
