This map is available in custom battles.
If set to “Sunny day”, the lake fills with water, which drowns you almost immediately. Artillery cannot reach across the lake to the other spawn, and you can’t make it to the islands without dying. So… amphibious vehicles, or helis coming to custom battles?
Good catch!
Would be cool to have amphibious vehicles in Crossout, although if they make it a separate battle it will probably be even less popular than air battles.
Ideally all battles could be ground/air/water, but unlikely to actually happen.
Hovers fly over water and acid, but will take damage from acid fumes. Hovers are also a great investment even if you only use them for art builds; I built a fleet of Star Wars ™ vehicles using them.
