What do y'all think is good from the Summer update so far? Personally I've enjoyed playing Cashworks the most in casual. Sulfur could maybe be a replacement for Steel in HL? Also it's nice to see Reckoner go official too.

This is BLU last; both the girders and the tiles are RED-coloured :(

Heyo, just figured I'd let you know you have a missing texture here. From my experience on other maps, this particular door is really prone to having this missing texture, so maybe consider replacing it with something? Up to you.

Cannot recommend this cool guy (https://tf2maps.net/downloads/tech-doors.578/) enough tho!
