Super Smash Bros. Source!

[Be sure to watch in 720p. Without it you lose way too much quality]

What would it be like if Super Smash Bros. had a Valve-only cast?
Set to the style and tune of Super Smash Brothers Melee, with elements from both Brawl, and the first Smash Bros. on the N64.

Special Thanks to Chaofanatic for Trophy Particle effects as well as the sunburst effect

So Heavy as Mario and Pyro as Bowser makes them rivals? crazyhalo just went and predicted the Meet Your Match Update

[UnmaskedPyro]

There's a parallel universe where we got something like this instead of Artifact.
I legit shed a tear thinking how amazing this would've been.

[blueman]

Real talk, Heavy would be such a fun character to play as in Smash.

[mint]

I spent a while thinking about the Heavy's moveset.

A - His default fists. A good jab move, and has two hits.
Side smash - A shot from his default shotgun.
Up smash - Hits upwards multiple times with the Eviction Notice.
Down smash -  A Russian Dance kick.

Special (B) - His beloved minigun, of course. He can move forward or backward while holding it down, but very slowly. It also has spinup time. But it's very powerful.
Side Special - GRU. He moves much faster than his very slow default speed, but takes more damage.
Up Special - He appears on the receiving end of a flip taunt of a random teammate, damaging when he lands. Distance and height is random, based on which teammate is summoned. They disappear soon afterwards.
Down Special - Sandvich! Can heal up to 100%, if he isn't interrupted.

Up tilt - Fires shotgun upwards.
Side tilt - A strong punch from his KGB.
Down tilt - Fires shotgun at the feet of an opponent.
Dashing tilt - Swings his minigun at an opponent.

Final smash - Ubercharge. Medic is summoned, he heals back to 0%, and becomes invincible.

Oh, and his taunts are the same. ("Kees me." "You, yes you! You are dead!" *Ding ding*)

I totally lost it when I saw Bloodseeker running along with Scout, I want this to be a real game
Also: "Source Arena: Slugfest"

[AlternateHistoryHub]

This was the greatest video I've seen this year. Congrats

[ixcaoili]

This isn't fair. You have the Gibus Scout Trophy, that's a Japan exclusive

[VulpineNebine]

Source DLC confirmed

Seriously though, why isn't this a gamemode in Gmod or something?

[Catzss]

The year is 20CT. everyone plays Counter-terrorist at KennyS levels of perfection.

[Link-phhc]

This is literally the 2nd greatest thing I've ever seen on YouTube...
This man deserves a Saxxy.

[neji]

This is so amazing. 
Now I want a "Valve All Stars".
Someone think of a better name.

[Sporkinator]

Smash Fortress! No wait... SUPER SOURCE BROS! No wait... Left 4 Smash Portal Fortress Life 2 Episode 1.

Master Hand is Gabe Newell, and when you beat him you get HL3

[SebbySenpai]

This just made me realize how incredible the Smash Bros soundtrack is.

BRB, listening to the 10 hour long version of Final Destination.
