Born on the forums of TWHL, here comes another collaboration pack – this time on the Source engine! Mappers were restricted to a small footprint for their map, as if each map were a floor in a tower. A full 3 years in the making, here is the result of a lot of hard work from both new and experienced Source mappers.

There’s a lot to love in this long anticipated collaboration! Enjoy the 18 floors in this solid follow-on to TWHL Tower and TWHL Tower 2! Plus don’t miss the handful of unlockable bonus maps!
