What to say about this: Overcompensating is the keyword here. Large area maps, lots of innovations and creative ideas made with Hammer (you can ride an airplane and jump a bridge with a jeep) but too many enemies. Sure I did finish this but I had to cheat more than once and left frustrated at the immense difficult level this had in many parts (specially for triggering fuel valves or finding what to do to turn on a teleporter). Other than that it was interestingly built with good use of assets and textures so I gave this an 8/10 in the review but it would be pretty much better if what to do was more explicit and enemy placement less repetitive (too many grunts in ep 1, too many aliens in ep2).

Please help! I just picked up the pistol and crowbar for the first time, but for some reason there is no sound at all when firing and no animation either. You can see your ammo supply go down on your hud though.

I have encountered a problem in all of the timeline mods. The weapons doesn't have any recoil or sound. Can anyone help me fix this?

Had a brilliant time playing these mods, a true work of art and a great part of my childhood :)
Nazis with the Ability to Time Travel, it's an awesome idea. I love the concept and the various locations it takes you.
Some of my favorite moments were witnessing the giant invisible monster held captive, seeing it break loose and such... and most of all being able to experience HG Well's novel of "The Time Machine" in the Half-life Engine. Genius. Through the detail you put into this chapter, I can tell you are a fan of Wells' work.
Wish you had made more, but for such a large and ambitious trilogy, I am happy it got completed. Not left unfinished. A great service.
Highly reccomend it.
