Units cannot attack in Water. Most non-flying enemies die in Water.
The Water Tile is one of the Tiles in Into The Breach.
Flying units are not affected by water. Massive units, which include all player Mechs and boss Vek, can stand in water but cannot attack. If a unit is on fire, it will be put out.
Terrestrial enemies with Explosive Decay will still explode on death, damaging adjacent tiles, when pushed into water.
If a specific Mech pushes a Vek into the water to kill it, it will gain all its XP. If a Vek is pushed or falls into water from indirect sources, its XP will be split between the squad.
If this tile is hit with a freeze effect, it will turn into an Ice Tile.
