- Physical hand interactions with door (ability to push open the door with your hand)
- Radio between squadmates/ in-game voip (open mic with 3d audio and radio PTT)
- Support weapons (kinda falls under the art category)
- Realistically sized doors
- Enemy dialogue variety
- Ability to customize weapon position in hand
- Ability to create preset loadouts
- Combat ambience would sell the immersion of being part of a larger conflict (for some maps)
- Enemy snipers
- Self and other player medical interactions for gameplay. In its barest form: a bleeding mechanic requiring yourself or another player to stabilize you. This would make getting shot a more substantial occurrence.
I'm really enjoying the game. I hope this is of some use.
