gp_airboat_race
This is a really old Gmod map that i often played with my friends.
I am not the author but i didnt find it on here and im pretty sure nearly noone knows it.
As you can see the map itself is pretty dark, (apart from the first screenshot where i
added a few lights) which isnt bad in any way because it allows you to build traps and
other scary things in the tunnels.
And if its to dark for you .. well just add a few lights to the track or to your airboat and
maybe a few trails and it will look awesome 🙂
All credits go to Snork who made this nice airboat map.
Here are a few vehicles that you may want to try on this map:
