http://steamcommunity.com/sharedfiles/filedetails/?id=310428958&searchtext=TTT Existential is a full-sized TTT map complete with numerous traitor traps. It is themed after an abandoned, city-17 esque labyrinth of a city. It is split into three areas, the bridge, the plazas, and the seaside. The map is extremely abstract, inspred heavily by the work of Shadgrimgrvy. http://steamcommunity.com/sharedfiles/filedetails/?id=303059376&searchtext=TTT snow map.
Existential: Size wise, it may be a bit of a problem. Although it does add a bit more to the whole usefulness of discombobulators to the map, same with Newton Launchers which I rarely see being used among this community. The only concern I have is that this map could have many goomba stompings occur. The two most notable areas for this being Spoiler Granted in the one off to the right of the screen, there's plenty of water...and a slight parkour which many will miss completely. Off to the left, just because let's face it...a majority of people don't know how to jump gaps very well, and will often miss them. Included with the ladder there which is one that you may find to be basically the same as the ones on Dolls. Not detail wise, but more use wise. The other parts being...where the planks that you can break with not too much of an effort. Just standing on some of them can break them with ease, but that might have just been my shoddy luck with them. As stated earlier, the size is...a bit big. Oh, and in a certain part of the map if you miss a jump, landing into the white and bright abyss, you will die instantly. It's a map that'd be quite fun if it were added into the server, though. I'll either edit this post or make another one for arctic soon. EDIT: Leaving Arctic for @Carned since I'm a lazy bitch and don't want to re-download Hl2 Episode 2.
Bumping with more thoughts about the map. It feels like rooftops, size and space wise in some aspects. Featuring both close and sort of far(?) areas. Would lead to many rounds being won if a traitor uses an AK-47 or Shotgun plentifully. I'm honestly surprised nobody else has posted here by now.
