I played it for ~30 minutes:
- There is no tutorial
- There is no mouse support on the menus
- There is no way to adjust the volume levels, and the game is stupid loud
- There’s only one option for the sound and its the voice chat, and you can only turn it on and off
- There is no tutorial
- The game froze on me when I entered the options menu in a match. The only way to get out was Alt-F4
In short
Lack of tutorial in a beta version of a game is not a fault. Nobody ever complained that Minecraft didn’t have tutorial. Same with, for example, Monster Hunter 4 demo on 3DS. It didn’t have any tutorial, besides showing controls. Which Metal Gear Survive does as well when you go into settings.
I agree with lack of mouse support, but let’s be honest, there is such low amounts of actual menus it shouldn’t bother at all
Lack of sound options is a pain.
The game freezing on you seems like an issue with your PC, I played the game for 2 hours and had no trouble whatsoever.
In all, this game seemed much better than I expected, I’m not sure why they decided to make it a “Metal Gear” series game, but overall the gameplay was pretty fun. It’s sort of like a cross between Left 4 Dead (zombies, horde mode) and Monster Hunter (gathering resources during missions that you use during mission to craft amunition, traps or other gadgets, or in the main camp to craft much better, more complex gadgets and new gear/weapons).
Instead of approaching this game thinking of Metal Gear and being negative about it, try to ignore the title and aproach it like a FPS survival for example.
