In Deep takes you through the scrapped version of Half-Life from 1997, re-imagined and revamped. What awaits you is a surreal, fast-paced, and action-packed journey through the old Labs once again!

This particular build is a small demo of the mod that contains Office Warrens (old version of Office Complex chapter).

Install by placing the "hlid" folder into:
Steam/SteamApps/Common/Half-Life

NOTE: This mod defaults to 106 FOV (corrected 90 fov for widescreen Half-Life) however if you are playing in 4:3 you must reset it to 90 with "default_fov 90" in console. If that is the case, you should also remove it from autoexec.cfg.
