Looks like hell and you can't even use a controller. Worse than the port before it. You can spend a fortune on a gaming computer, but if you want to play this you have to go get a PS2 or an Xbox. Embarrassing. GOG owes me some god damn money.
Don't play this on GOG, they butchered the Psycho Mantis fight. Kojima didn't design this game to played on a keyboard. If you are playing it on a keyboard, the fight isn't even special. Forget this.
