I can’t believe I have to repeat this.
You CANT use natural cover in a game that wasn’t intended for the usage of natural cover. Most maps are very open - with very little consideration for the usage of natural cover, hence why you rarely have spots that you can peak from or hide behind and still get work done.
On top of this - this game has never had the features for natural cover. You cant lean, you can’t lay on the floor, you can’t tilt.
This game was made with shields being intended as the primary cover.
