Before you even start playing the game, you'll need to do some things, in order to run it in a decent way. That's what worked for me in Windows 10 1803: *Go to the install folder, find "MessiahD3D.exe" *Create shortcut of it, add "-i -x +!" parameters so the final path would look like this: "E:\GOG Games\Messiah\MessiahD3D.exe" -i -x +! *Fire it up, set resolution *Set desired framerate in game menu (I reccomend 30 fps) Ready? Your game should run pretty decent right now, so lets get to the gameplay... And boy, this is diffrent. First of all, you will reconfigure your keybindings and you will configure your mouse input. This game is immposible to play on it's default settings. Oh yeah, I was suposed to talk about gameplay: imagine half-life in third person, in a really, really twisted world, with awfull aiming control (well, it's auto aim), being able to possess ANY living being, and really unique fighting mechanics. I nearly quit playing becouse of it, but belive me, once you'll get the hang of it, it is pretty fun. Graphics? 10/10, I love this game art style. Audio is quite bad, but the music makes up for it. Overall, even with 4 stars, I would reccomend this game to evreyone. It is a really nice experience without any nostalagia grown to it - I was 4 when this game came out, and I first played it 20 years after release.
