The first five MODs to ship on steam will be Age of Chivalry, D.I.P.R.I.P., Insurgency, Synergy, and Zombie Panic. As always, owners of any Source game will be able to download and play all of these MODs for free." Mods hosted on Steam will also use Steamworks for stat tracking an other community integration. Once installed, these MODs will appear in your "My Games" list and will receive automatic updates just like other games on Steam.
