How is this version of Quake 2? Its alright. Keep that in mind.

Unlike its predecessor, Quake, this came after some of id Software split. Therefore, it changed what the game might have been. Its mechanics are somewhat different from the original. Expect barely any ambiance like Quake 1. Trent Reznor turned down this game after he saw it: now for some that is a red flag. Its not. You instead get a metal soundtrack, which is really good (created by Sonic Mayhem). The deathmatch, as I have heard, is pretty good. The action in this game is really good for a sci-fi shooter of the time. The best part for gib enjoyers? EVERY SINGLE ENEMY GIBS.
EVERY. LAST. ONE.

Now, this game lacks SOME things that would make it good for a modern release (keep in mind these are Quality of Life improvements). Unlike Quake 1, which got a huge makeover in terms of the system, this game is running out of the command prompt. That isn't bad at all. However many people want the systems from Quake1's new port carried over to this. It would help the game tremendously and may up the player count.
Another thing, just separate from the rest... The expansion packs are sold separately. The new Quake remaster added all of those in the game, while you'll still have to grab everything for this (unless they remake it as well, which would be nice.

I'd say its worth the buy!

I've played it a few times on occasion and I know what the problems are, yet whenever I start it, I am immediately attracted by its nostalgia and its power. It starts with the menu screen, the one you see in the opening moments, where the black screens keep popping up, but instead of helping you to keep focused on whatever the hell you're supposed to be doing, they invite you to keep your eye on them. Like, literally, they bring you into the game. And they make you feel like you are doing something important.

Unlike first Quake, story makes sense now.
In the previous game you were wondering, what the hell am i doing, what is the meaning of all this? Knights? Soldiers? Zombies? Boogeyman? Why everything is stitched together like Frankenstein's monster?
Quake 2 story on the other hand makes you play as soldier, trying to conquer the big storage room filled with nothing but crates and boxes (accoring to level design) from the Borg species, on a distant planet.
And it's the only good thing about Quake 2.

Gameplay and level design mostly left unchanged and frankly, i don't give a damn anymore.

Now i know why this game is still single, it has no depth.

10/10 - Legendary.
