If you never played this, you have no idea what you're missing out.
All the greatness of the original, with significant quality of life improvements that allow the player to enjoy the full original experience on a modern machine (with music too!). If you don't know which one to buy: I recommend to buy this version. If you never played Blood: play it. The best of its time, still a stellar and fun game with an atmosphere you won't find anywhere else. This is not you banal moder shooter.
Best FPS arena ever made, and also the model after all the others have been made. One of the best FPS games ever made in general, under all points of view. Also, crazy impressive AIs, I still play against bots a lot and it's just great, very rarely I get NPCs stuck and lose the illusion of playing against real people.
The game is "Meh". That's just the best way to describe it. I see the effort that was made to create it, but still a "Meh" game. Musics are royalty free stuff you can find on the web. Sounds too. Cute story but clearly made by an amateur without any knowledge of story telling. The gameplay is fine, the game is clearly a "Portal-wannabe", but definitly lacks the mastery to create such a compelling and deep gameplay. For its price is fine, it gives a bit of enterteinment.
