It didn't start. I'm sure theres a mod or something to fix it, but if you buy a game you expect it to at least start. It says that it's optimized for Windows 10, so I don't know what it is.
I've finally managed to get a very short time in on the games first level, I persevered with the controller setup in many GOG games I find any kind of none defacto gamepad a real pain unless it's made to be played with one natively.
Even then there are some games rejecting certain gamepads and unfortunately the age of RTCW means it won't conform to use gamepads in a native way so the the way to force these games into using gamepads is Steam (I know) add your games by the add a non Steam game and choose WASD to gamepad and map with that, AntiMicroX for me does not work for this game in Windows 11 but Steam Input WASD does work.
Any way for what I have played it is relatively fast aced and quite hard to master the aiming when mapped as it is swift like a mouse obviously for the view controls being bound to the mouse, but it is a good game for it's time and has reasonable graphics for that time to, although it's struggling to hold up to other games of today the graphics are acceptable.
It's shoot first or be shot gameplay style with a high level of challenge.... on the Hardcore setting of difficulty only a few shots really and your dead meat.
The weapons are pretty basic in the first stage obviously they would be, they will improve as you progreess they pack a light punch nothing overly beefy really, I do like the era/thematic setting and the locations which find you facing off against the N@zis in a WWII timeline. It does draw you in and you keep wanting a bit more but it can be frustrating with that difficulty level and a low hit count before death even on easier settings it's quite hard.
It's a straight forward pick up and play slayem and mahem game making a bold attempt for it's age at trying to be a cinematic epic of sorts, although it's nowhere near the modern versions of the game reboot/s in respect of that, they are amazing comparitively, but you can see where it's spawned from and it's a gem of an old game.
When this game came out, I was smiling playing for hours on end. When they made the free online version I played it until the next Wolfenstein online game came out. Great memories, even then we had more then Nvidia and AMD going at it for the best GPU at the time lol.
It's a very complete game, very varied, with lots of weapons, varied mission settings, good difficulty, good bosses, and a simple but very good story. It's almost perfect despite being so old.
