I have edited GM_construct to make useful in TF2 as a CTF map.
There are some bugs in this version. I'm going to upload a fixed version ASAP.
Things I've changed:
*New Rooms and elevators
*CTF and spawn rooms
*Slight texture changes and a few building layout changes.
Version 3.1 and later:
New command File that can be used when sv_cheats "1"
type into the console:exec gm_construct_cynder_dragon_loves_portal_remake_a3
Version 4 is currently under the testing phase.
