You have a real problems with ui for now. For example, i can see the descritions for different guns available, but have no idea how to switch to them. It's not explained anywhere at all, i can only zoom in, and that's all. What character points and other values doing? What everything else does? I don't feel comfortable with menus that not really user-friendly.
P2P mode is a terrible choice. in 80% of games i played i had sudden host migration and mission chapter resstart because someone decided to leave or was disconnected... That's especially great with boss almost dead and going back to full hp.
Not sure if beta has only 2 missions or there is no info about how can i unlock new ones.
Also, the antagonist gameplay is not rewarding at all. Who cares for silly rating board? Why can't we recieve at least half as much as players get for their play (and more if you defeat them)? In this game, if you want to play as antagonist - you must chose between progression and fun. And that's a terrible choice.
Rest of the game feels fine, but antagonist's spawn points should be adjusted. There is a few locations where he always spawns too far away and only from one side, no way to make and unexpected attack, people always see him coming. Spawns should be everywhere around, so players have to keep their guard up all the time.
Also you should really sent more keys out. Me and my friend were waiting for so long but got only one key and can't play together... And matchmaking takes from 30 minutes to full hour to find a game. You need more active players to actually test the game...
