The Hiisi Gunner (in-game name Rynkkyhiisi) is a flying enemy commonly encountered in a variety of biomes. The player will usually first see them in the Snowy Depths.
Hiisi Gunners hover slowly with their jetpacks and fire alarmingly accurate bullets at the player. Their shots arc slightly as they fly, but still have enough range to hit the player from off-screen. The gunners are often seen in small groups accompanying Grenadier Hiisi, or accompanying a Hiisi Leader. If shot while hovering they will sometimes be knocked out of the air.
Their attacks deal 4 damage and temporarily disable levitation.
Their weakness is not being able to shoot vertically downwards, making them vulnerable to attacks from below and above.
