I've released new versions of Hook Mod, Ent Mod, Radio Mod, and AdminOP 3.0 Beta. AdminOP 3.0 Beta is, like before, an upgrade from 2.0 -- not a separate installer. You can get AdminOP 3.0 Beta here. The other mods can be found in the download section. Included in the zip files for Hook Mod and Ent Mod are help files that should explain most things in detail. The Radio Mod help file will be ready hopefully not long from now.
In the new version of Hook Mod is the option for a swinging hook. This idea and the math behind it comes from the generous permission of SpaceDude who made an amx plugin like it. Also, Ent Mod's admin bug has been fixed. All the mods have been made compatible for Steam and the newest Metamod.

Note: If you won't be using Steam for AdminOP and would like to run it on a LAN server on the old Half-Life TFC make sure to put DF_steam2 0 in either server.cfg or AdminOP.cfg.
