Alright well I've been playing this a lot and it's just so ******* awesome I have to review each part.
This review is for Timeline 1:
I loved it! The concept is very interesting. The mapping is bland in a few places but no worries I still liked it. The Nazi concept was amusing too. If Wolfenstein and Half Life had a baby, this mod would be the newborn. Anyways, here's pros and cons:
Great idea for a mod
Awesome story line
Cool textures
Awesome locations
Perfect lifespan
And overall, a great concept for a mod!

Bland mapping in some places
Some puzzles that were a little too tough and vague
That's all!
In general, Timeline 1 gets a 10/10, even if it does have minor flaws in places, the atmosphere and idea of the mod is what makes it well done!

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.

Timeline 3: This I feel is a rather disappointment considering how great a improvement the previous timeline mod was. Here the Nazi's are actually still alive because they have solidified them selves into many timelines so they still exist (eventhough their timeline was destroyed... shouldn't it have wiped out whatever they did afterwards?) The mod gives some weird explanation of how they have a temporal distortion device blah blah, what ever the explanation we get to fight the nazi's again.
The mod continues its variety of locations and gives us 4 'into the future' locations rather than 'in the past' like the first timeline.

The 1/5th of the mod takes place in the Nazi space ship, that eventually lands before we have a chance to get out. The level design is here pretty awesome where we get to see a big space ship, while it remains challenging it also kind of makes us back track! This is a bit of a let down for me.
Once you go outside and take a truck and find a key card you have to go back, took me about 10 minutes to figure out that you probably have to go to the start of the level and try to open doors with it.
The game did not tell you or even hint to you that the one of the doors needs the key card. It had no key card slot so how was I supposed to know?

Shortly after you have to find 2 key cards but they both do different things, one is for the satellite room and the other is for the bottom area of the ship hanger. I had to run back and forth a bit to figure out what to do with them. Bit annoying.

After this things go weird. You go into the future of some sort of automated AI that keeps the planet under control in case something happens to the human race. You have to go and blow up Nazi generators across the timeline but
3 out of 4 of the locations are all in the future this time.
When I first saw that one of them we get to travel to early 1990's London I was quite excited... only to find out that it lasted for about 5 minutes before we get another time machine and go into the future... sigh.
Thats a real shame because it sounded like the most interesting environment yet.

Then the mod ends on a rather obscure/sad note. Totally a Deus Ex Machina. Lame move not to mention when we jump into the vortex for some reason it only teleports us into dangerous places... how does that work? Nevermind, the author was obviously tired of this and its a shame it ended like this.

+Some very unique environments in the future
+They all have some very unique texture work
+Quite a challenge
+Very long

-A bit to much running around! When you blow up a generator you have to run all the way back... hurts the pacing.
-Obscure puzzle that requires you to back track and open a door with a key card that has no key card slot
-One of the future places was rather short and simple with that pyramid.
-London was extremely short, less than 5 minutes... I was so excited for it only to be taken into the future again.
-One area has infinity spawning grunts, and it takes some time to find out that you just have to go back into the teleport room.
-A somber ending

+- You get to revisit Black Mesa

The mod DOESN'T end in that "meaningless place". First you walk to the monitor and read the Gman's message. Then you have to walk to the transmitter and put one of the rods you picked up before in Thames Valley. Then you step into a teleporter and go to Berlin in year 2002 and the mod continues. There is a good portion of the mod left for you to complete. The real ending is 100% satisfactory.

I really love this mod. The places you visit, London 1899, Thames Valley 802701, and the two distant future Earths, are based on H.G. Wells' The Time Machine. You even get to visit H.G. Wells laboratory in London where he built the time machine (in the book, obviously).

Timeline 2: Theres so much to like about this one. Where do I begin.. first off its better than its predecessor by a mile, It's got everything going for it, a unique environment that stays fresh till the very end, challenging fights with little health and just enough ammunition to keep spare, and a huge length.
The environments are so well designed, you go through a research station out in a god knows where but theres so much snow and even ice is used to some effect when traversing hill sides to give it a sense of danger without using the same tired old, "ledge breaks when you step on it trick".
You go through a small Xen part which is mostly just bunkers built on Xen so the author knows not to risk trying to do a proper Xen level because 99% of the time people fail at it.
You again have to take on Nazi's but this time they managed to get a secret weapon. And my is there alot of things to do on the way there...
The game starts off slow, taking about 15 or so minutes before the first battle so it sets things up nicely and gets us to focus on our surroundings which are dam fine. I like mods that can take their time to introduce us & build some anticipation for whats about to come.

There are a few small puzzles, I don't mean just the usual button pressing (there is some of that to be had) but a puzzle that requires turning valves on to start water which also barely counts as one, no the small puzzle is a fetch quest for a key card to turn on a teleporter which had me scanning the place for at least 20 minutes. Turns out theres a hidden place underneath a elevator I forgot to check -_- Mods that put obscure locations like these really need to think about treating places like these as "secrets" & not mandatory areas to visit to continue the game.

A boss battle that was hard in a way that may seem annoying to some with the constant respawning Islaves... especially for me because I was very low on health.
But wow does the mod maker now how to make his set pieces, because some like the bomb and the sled, cable car, light weight plane where wow moments for me.

+Excellent level design, Unique environment thanks to new textures, Good pacing, Challenging, Some great set pieces, Very long
-Tough boss battle in a way people might not appreciate, One tough unintuitive puzzle, Story was rather simple
