Favorite: The Phalanx version of the Gladiators. A particular thing I liked about this game was how cool the energy shields looked on the enemies, so I was glad that it was implemented on my favorite common Strogg from the original Quake II.
Least: Laser Guards. These guys were a little too common and were especially annoying when they hit you from behind or the side. The blinding effect of getting hit adds to the frustration of tracking them down.
