I just fired up HL v18.104.22.168 with FLF v1.2 and Oddbot 1.8.1 (not the newer metamod Version, the old one) and it ran like a charm.
While bots never can replace humans the gameplay was surprisingly good and really brought back a lot of the old FLF charm.
Here's a vid on icehammer (yeah, icehammer, of course!):
If anyones interested I can up all the necessary files ready to game.
