These are, in my opinion, the best Single Player Source Engine mods.

(This list does not include mods for other games, including GoldSrc.)

All these mods, unless otherwise stated, are for a Source SDK base, Half-Life 2, Ep1, or Ep2.

If you know of a SP Source mod that deserves to be on the list and I haven't reviewed let me know and I'll play it.
