I was rearranging a closet and came across an old CD case for the PowerPC Mac version of Freedom Force from something like 2004. I actually still have a PowerPC Mac but it's a laptop that needs a battery and a PRAM battery so it's just a closet creature at the moment. Then D'OH I remembered I have Crossover. I looked for the Windows version of the game on sale online and learned about GOG.com. They had Freedom Force on sale for $1.24. That wasn't a big risk so I decided to buy it. I had to create a customer account on GOG.com then a quick transaction with Apple Pay and it was ready to download. Freedom Force worked perfectly on my Mac with Crossover so I decided to try Freedom Force vs The Third Reich – which I had never played because there was never a Mac version of that game. So after some testing of Freedom Force I bought Freedom Force vs The Third Reich, too. Freedom Force vs The Third Reich was also only $1.24.
It's important to download the "offline backup game installer" version, not the normal GOG version. The normal GOG version includes GOG's proprietary installer/updater and I couldn't get that to work with Crossover. But the "offline backup game installer" i.e. the normal installer for the game worked with no trouble and the game functions perfectly! If you have old saved game files (I don't because I never played this game before) all you need to do is get them into the correct directory for saved game files...

I installed Freedom Force vs The Third Reich into the same bottle I created and used for Freedom Force.
I'll note that I installed DirectX for Modern Games into the new bottle I created for Freedom Force before installing either game into the bottle. This probably did nothing, it's more of a habit on my part and I had done it before even really thinking about it. Since this game predates most or all of the stuff that gets installed by DirectX for Modern Games it's unlikely that it's doing anything other than taking up space. But it's not hurting anything, either.
Time to clobber some Nazis. For freedom!
