I think this is a better expansion than Blue Shift, I think the level design and enemy variety is a lot better, also the game is longer. Still not the biggest fan of Half Life 1's combat though. And also there was this constant glitch that happened where sometimes I'd just get stuck in place for no reason forcing a reset. It was an ok shooter, the lore it added to the Half Life universe was pretty interesting, so I can say I am happy I played this.
