Chomper is a boss encountered in The Nameless City. It makes its appearance in E3M3: City of Shadows and is exclusive to that level. Chomper resembles a large, red fish with a gaping maw.
Encounter
After successfully acquiring the red key and opening the well, the player will need to jump in to acquire the yellow key. After navigating a short tunnel, the player will come across sunken ruins with a large, openable wall on the opposite side of the room. Once opened, Chomper will rush out and begin to attack.
Tactical Analysis
Chomper spawns with roughly 7000 health, making it an average health boss to fight against. Its main method of attack is to fire a spread of blood shots that are similar to the Black Phillip's, but slower in speed. This spread encompasses around eight to nine shots and is signaled by a distinct noise. Chomper also tends to move away from the player, preferring to huddle in a corner until fired at. This makes the boss one of the easier fights in The Nameless City.
As with most bosses, Chomper is weak to stronger weapons like the Riveter, Hunting Rifle, and Crossbow. However, the fact that the fight takes place underwater renders weapons like the Mortar obsolete. Additionally, the player's movement is slowed underwater, making it difficult to dodge Chomper's projectiles. A good strategy for fighting Chomper is to use mainly hitscan weapons like the Hunting Rifle or Assault Rifle. The Sword can also be used to deflect any stray projectiles from Chomper's spread.
