I used to play a demo for an old shooter late 90’s with sprite-based NPCs, and a lowres realistic art direction. You would start in a area with grass, facing two NPCs wearing blue (allies) in front of a fence. Enemies were in red, and the level had a path in the river too.
I’ve never been able to find what game it was :’)
@Nexus5 thanks but that’s not it :) it was more like Duke Nukem 3d but realistic military art direction
