Crimson Mountain is a medium-large outdoor map created mainly off terrain and with ruins placed around it. The environment of the map is an ancient / medieval type and the action takes place on a mountain covered in a dark red fog. One thing I wanted to add were torches but sadly I couldn't get func_pointparticles working well in the SVN so I couldn't obtain a good fire generator for them. One feature of the map is that first of all, it's a terrain based map... the terrain is created in the same way as ONS-Reborn's. Another thing is that I went very in-depth on using caulk on every single hidden surface that I found, and unless I forgot something every surface that doesn't display is caulked. I also made sure to add hint brushes all around the map and applied player clips everywhere they were needed, especially around the borders so people couldn't get there to see the fake terrain edge.
My worst regret about this map is that I ran out of both energy and ideas alike to add more detail around it. I added something in every place so the map won't appear as an empty terrain but I'm still not sure if that's enough. Don't think my map will make it officially because of that (that's up to the developers but just for the note if anyone wants to include the map with the game that's perfectly ok for me if you think it's good enough). The main reason I wanted to make this for an official map is that I want to encourage making more terrain maps around the game and officially into it, since Reborn is the only one so far.
Gametypes I included are: DM, TDM, LMS, Rune, Keyhunt, DOM and CTF (the CTF version is on the same map since no geometry changes were required). Download locations -here- or -here- if the first link doesn't work. A few screenshots of the map here:
One of my favorite games.
