TWHL3 feature - Polls!
Anyway, what (Half-life 1/2) mod do you think had the best training level? It doesn't have to actually be a training level, but the map that is selected for it (If you know what I mean)
My top 2 would have to be:
Azure Sheep - Pre-disaster thingy
Poke 646 - Bootcamp (I think :D) , but better than opposing force.
