This game came right after the peak of Medal of Honor when the dev team of that game started to splinter. It's a fun shooter that starts off very slow with the set pieces but picks up the pace nicely after a while. It ultimately became overshadowed though by the rivalry between MoH and CoD and never got a second chance even though barely anyone touched the Vietnam war since. On modern hardware it runs pretty great on Windows 11. The only problem it doesn't boot up right away and it's only windowed but that's it. Certainly worth a try to see what could have been the alternatives for Call of Duty if history went a little different.
