Ah, that's a shame. It would be really good in this mod https://forums.alliedmods.net/showthread.php?t=314630
if you know a plugin that adds Versus mode effects like Hunter pounce damage and Smoker tongue drag damage to campaign co-op mode let me know, I've been searching recently, tried this mod for that mod in the link, doesn't work for campaign which is a shame. Anyway let me know if you have the time.
EDIT: oh yeah, in the mod I linked you the hunter can leap from 1500 away and if this mod worked in campaign it could seriously land some 30 dmg pounces in some scenarios, its tailored for pros and the SI are really good at combating good survivors
