I would suggest trying a new game without the food & water need. It really lets you focus on the plot. I also needed to look through a few YouTube videos at various points, because some things aren’t obvious or are easy to miss.
Was just thinking the same. A happy trip down memory lane. We used to do quad jump + low gravity + instagib. There was some capture the flag map that was great with these mods. I can’t remember the name now though.
