I recently had the pleasure of playing Wolfenstein 3-D : Machines of War, which is the 1st and 2nd free episodes to Jazz Software's action packed, first person retro inspired shooter, and let me tell you it's GOOD! It's not a remake of Wolfenstein just fan based episodes, but it does feel so much like the original game from the retro soundtrack and Nazi voices, to the classic action packed movement we've come to love from the original title. Although the tile textures are further improved from the original, the enemies remain as close to the classic pixels as we remember. The only downside I could find so far in my play through was the amount of times I got stuck in between bushes and I was even being shot from an invisible enemy, but apart from those flaws I'd still highly recommend this gaming retro inspired series.
