Gigazark (剛波五連砲ギガザーク Kōha Gorenhō Gigazāku?, lit. "Heavy Five-barrel Cannon Gigazark") is an enemy in the arcade and MSX2 versions of Contra. It is a more powerful version of Zark turrets from base stages, that serves as a primary weapon of Gromaides.
Description
Gigazark is a turret, that shoots five bullets down in a spreading manner. Just like Zarks, it can only be damaged when it opens for attacking the player; otherwise, it will be invincible against the player's bullets in its closed state.
This large turret only appeared in the arcade and MSX2 versions of the original Contra as Gromaides's main form of attack. Other ports of the game changed both the creature's design as well as its form of attack, using projectile shooting tentacled limbs instead.
