Oh, I could finally play the two episodes!

Nah, it's probably best to wait until they finish all the episodes then play them back to back.

It looks like Team Fortress Classic is free as well. I would have asked what's the best way to play TFC with 2-4 people, but I remembered Half-Life has multiplayer deathmatch in addition to a campaign.
