Would have given this a higher review but hey, playing the Reckoning my saved games stopped loading and when I tried some Yamagi mod, those same saved games disappeared. We don't live in an age where someone should have to mess around with nonsense like this to play a game.
As for the base game. No music. Music files are supposedly included, but why aren't there programs included that mounts or uses that music automatically? Why do users need to again, futz around to get stuff working? Whether its Steam, GOG, or Bethesda that's at fault, there should be a soundtrack with these games. Do the extra work, and get it done.
As for the game itself. Pretty bog standard marine sci-fi shoot 'em up. Same id Software weapons that you see in most games, the guns could fit right into Doom 3. The story is completely throwaway, and while the technology in the game was probably very impressive for the time, it's also completely overshadowed by Half Life that came out a year later.
The game itself, can be fun at times. But as with the first Quake, the problem is the enemies. They're just not that interesting, for the most part. A lot of cyborg soldiers which aren't that distinguishable from one another. One prime example is the flying enemies, which consist of a VTOL-suit guy, a spaceship type drone and a garbage can drone. These enemies all seem to fire the same gun. The only difference is hitpoints and target size. Why do they all exist? Compare it with Doom 2's three unique flying enemies, the Cacodemo, Lost Soul and Pain Elemental. It's night and day. You can argue maybe that the enemies in Quake 2 are more granular, but they are less iconic.
I don't think the game rides the tension line very well either, maybe it was because I was playing on Normal but the game was pretty easy once you get the gear. But I don't think there are a lot of big fights and big moments, and with the exception of the railgun enemies, most enemies don't feel that dangerous. It's OKAY.
