Sure not literally perfect, but overall, what more of it can you ask?

Every level is instantly recognizable, so unique. The different texture/sprite themes are fantastic and very fitting. The maps with the sector lightning made it very immersive, I always wanted to see the next level and keep going. All enemies are recognizable, original designs. Same for the weapons. The sounds are cool, the music is great. A lot of stuff to do for a 1996 game. Very creative.

While not as technically impressive as Quake, I had more fun playing its SP than Quake which by the time I finished episode 2 I was having an headache with the constant brown-ish theme.

Damn, im looking good.
