[THEORY] All the Valve games are in THE SAME UNIVERSE!

[GoatCart]

I have a theory that all the Valve games are actually in the same universe. I have facts to support it too! Here is how the timeline would go:

The first game in the timeline is Day of Defeat and Day of Defeat Source. These games take place during World War II, so they would take place some time between 1939 and 1945.

Next is Team Fortress Classic. The TF2 comic, "A Cold Day in Hell" shows that Team Fortress Classic is canon, and takes place within the same universe as TF2. My guess is that TFC would take place 5 or 10 years before Team Fortress 2. This would set it around 1940's or 50's.

Next comes Team Fortress 2. Calenders in the game, and dates in media and comics, state that it takes place around 1960's or 1970's.

The events in Portal, Half Life, Opposing Fource, and Blue Shift probablly take place around the same time. We know that the Black Mesa incident takes place within 5 years before or after Portal. Portal takes place around 1999 or 2000, so the first Half Life games would be around late 1980s or early 2000's.

Next comes Counter Strike games. These games obviously take place before the Combine Invasion, or before the Black Mesa Incident has any effect on the rest of the world. Based on technology and the locations this game should take place somewhere around 2000.

Next comes Half Life 2 and it's episodes. Valve stated that Half Life 2 takes place 2 decades after the first Half Life, so that would set Half Life 2 around the 2020's

Portal 2 would take place after the Combine has been defeated from it's takeover of Earth, because in the ending of Portal 2, when you portal onto the moon and you can see Earth, the oceans are not drained of water, and there seems to be no Combine technology, thus implying that the Combine no longer have control over Earth. Based off of the amount of deterioration to the Enrichment Center, and the expiration dates on the Longterm Relaxation Vault containers, Portal 2 would take place 20 or 30 years after Half Life 2, so it would be 2040 or 2050.

Now comes the Left 4 Dead series. In the games, a zombie apocalypse has occured. There is no evidense of a "zombie apoclypse" in the Portal or Half Life games, and the game could not take place before Portal, because of the time period. So this sets Left 4 Dead sometime during or possibly after Portal 2.

After that is Alien Swarm. Valve offically said that this game takes place in December 2052.

Finallly is Dota and Dota 2. This one should take place EXTREMELY far into the future on Earth, or on some other planet.

EXTRA STUFFS:

At some point the Space Core crashes on the planet Skyrim takes place on. I'm not sure is this can be considered canon, but if it is all I know is that this event takes place some time after Portal 2.

I hope you enjoyed my theory. I think it makes sense, but it really depends on the opinion. Thanks for reading!

it makes perfect sense except for your lack of info conecting tf and l4d to p2 and hl

Wow, going way to deep bro, think simple. Connecting all valve games is just... come on. It was shocking enough to find that portal and half life universe is connected and that made a lot of thinking, discussing and brain malfunction.

Valve made Portal 2 story ( in my opinion) in a simple way, but as well made it hard to notice it. As well, it seemed it gaved us alot of answers to portal story, but it more looks like they gaved more questions.

Plus, they WANTED to not connect these 2 games as much as possible, keeping it on a string rather than a rope. Giving some things that connects to hl universe (Borealis, Aperture itself), but not much that it would make some sort of impact to hl.

[Ozyruz]

No way!

*Whispers*
I knew this already...

[_Soj_]

Dude, what have you been smokin'...........

[Sultan]

Thanks.
We all know that already.
Just I am not sure that they ALL are in the same universe...
Maybe not L4D and also the counter strikes.
The counter strikes are in a normal world I think.

Just gonna put this here if you haven't seen it: youtube.com/watch?v=RKseCg8wuBk this is too significant to just be a reference (serious note that g-man is in there as well). Also, at the beginning of portal 2, the pre-recorded guy says "We are currently experiencing technical difficulties due to circumstances of potentially apocalyptic significance beyond our control," the key word here is apocalyptic as in zombie apocalypse. And the CS series is just going on somewhere else at a different time, not very important in the over all plot though. Just no one get angry at me for my crappy punctuation grammar and probably how wrong I am. :/

That's refering to the Combine takeover.

Ok, sorry, forgot a bout that, where was my mind.
Other point: The back story of Bills Hat in TF2 is that he has fallen throught an Portal throuhgt universes, so L4D2 (and so L4D too) cant be in the same universe like Team Fortress, but a good theory.

[Zesc]

Ok, other thought:

We know that L4D (i mean L4D & L4D2) is in another universe than Team Fortress. But Team Fortress is in the same univers like Portal (App-Sap), and Portal in the sam universe like HL (nothing to say). Let's count: TF-/Portal/HL-Universe + L4D-Universe = 2.
But cave Johnson talked about other Multiverses, i counted 7. 7 + 2 = 9.
But when the L4D universe is identic with one of the Multiverses Cave Johnson talked about (Probably the Multiverse with the Evil Cave Johnson). we have Just: L4D-Universe + TF-/Portal-/HL-Universe + 6 = 8.
This means Valve made a minimum of 8 Different Universes.

You didn't connect L4D to anything. Just because there's a zombie apocalypse doesn't mean it's related to Half-Life or Portal. The same with CS. Just because it takes place near HL and Portal doesn't mean it's in the same universe. For me, only Portal and Half-Life exist in the same universe (for obvious reasons {Mentioning each other}). Also, Portal 2 is like, centuries into the future. The tv screen broke because the time was so long, and it couldn't comprehend the time so it tried reading the time, but could only go '9-9-9-9-9-9-9etc" (and succession usually takes at least 70 years. Aperture looks like it's been excessivley exposed to succession. (If that's how you would say it.)

[Jeff Simulator Really Cool]

theres an easter egg where there is a tf2 action figures riped ad in in l4d2 so maybe the tf2 figures are like toys in the universe

Connecting Portal to Half Life is easy: It's shown and said in both Portal games that Aperture and Black Mesa are fierce business rivals, with Black Mesa stealing credit from Aperture and passing Aperture's inventions off as their own.

Connecting Portal to TF is also easy: There is an item for the Spy in TF2 called the Ap-Sap, which replaces the default Sapper he already has. The Ap-Sap looks like Wheatley, a character from Portal 2. The Ap-Sap also uses dialogue from Portal 2 as well as custom-voiced dialogue for TF2. The description for the Ap-Sap says that Mann Co. made a business deal with a nice lady in an abandoned science facility for a whole bunch of Ap-Saps. This 'lady' could be refering to Chell, the protagonist of Portal or GLaDOS. Also not directly referring to Portal is a Companion Cube Pin, a pin for all classes that looks like a Weighted Companion Cube coming out of an orange/blue portal.
