Grenadier

Grenadiers are one of the first long-range enemies encountered. They have a much larger aggro radius and can see the player through walls and floors. Grenadiers are gradually replaced with Bombardiers at higher difficulties.

Behavior
Grenadiers can detect the player at longer distances, even through walls or on a different platform. At BSC 4+, they will not teleport after the player.

Grenadiers can backstep to avoid the player when close.

Elite Grenadiers have only one change added to them, in that their bombs explode as soon as they hit the ground.

Strategy
Grenadiers are one of the first long-range enemies the player will encounter. While they are vulnerable on their own, their large aggro radius makes them a nuisance at a distance. This is especially a problem if you are fighting other enemies. Depending on the stage layout, it can be difficult to get within range to kill them. They are rather slow, so the chance they can fire another shot before dying should not happen often.
