Wanna make the bots more useful? Do you want to watch them throw grenades like you wanted to? Did you expect them to...... Naaahh, you already get the point.
No convars, commands, or anything unnecessary. Just simple drag and drop.
Notes:
(L4D)
- Gear Transfer is needed to make the bots grab grenades. Also, the options where bots can give grenades must be disabled.
(L4D2)
- Do not use this along with Gear Transfer as it conflicts with the Left 4 Downtown 2 method.
- Bots will not pick-up grenades without the extension unless you have the Gear Transfer plugin installed but expect bugs.
