Bat

An uncommon foe, the Bat is the weakest enemy in Catacomb 3D in terms of Hit Points, but makes up for this by being one of the fastest foes in the game. They look like oversized black bats.

In Catacomb 3D
The Bat has only one Hit Point and its damage is the same as the Orc, but it is much faster and intentionally zig-zags left and right to try to close in on the player. A single uncharged shot will destroy one outright, but the Bat often makes up for this by appearing in sizable packs. This, paired with the jagged nature of where they fight you, makes it very easy for them to corner you. Rapid uncharged shots are your friend here.

They appear only in The Warrens, and Hidden Caverns.
