You don't have to go THAT slowly!

It started as a simple hack for speedrunners, and now aims to be the greatest toy box the Portal 2 Speedrunning Community could ever receive. Portal 2 Speedrun Mod is a modification that alters the way you run through the default Portal 2 campaign. Not only does it remove most of the cutscenes and waiting, making the game a lot more entertaining to speedrun, but it also introduces several game-changing modes, giving a fresh experience of your favourite test chambers, allowing you to enjoy them in a new unique way.

Credits

This project wouldn't be possible without the help of these individuals:

Nanoman2525 - creating the Coop Speedrun Mod mode.
NeKzor - creating a base (Chaos mod) for the SMSM plugin and massive support during its development.
Blenderiste09 - Chapter 9 scripting & testing.
BigDaniel - motivation so large that it deserves a separate credit.
Valve - creating the original game.
A bunch of generous people - supporting development of this mod. Find their exhibit in-game!

We also thank people who helped debug and beta-test the project, including, but not limited to:

Can't Even - live testing.

BreweryJake
Rex
Spidda
Turkey, Façade, Oatsy, Soulfur - Coop testing.
..and a bunch of other people we forgot to credit (sorry :/)

Although Krzyhau has moved on from this mod, the Portal 2 Speedrunning Community is still maintaining it and adding new modes and features. We are grateful for his work and dedication to the project. The mod is currently being maintained by:

AMJ
Betsruner

Normal mode (Now featuring coop!)

The main and original mode of Speedrun Mod. It's also a base for all the other modes.

Most of the game's downtime is removed or shortened (like elevators, doors etc.)
Most of cutscenes were removed or shortened (like Tube Ride, Core etc.)
A full list of every change can be found here.

Celeste Mode

A bunch of berries were scattered around Aperture. Dash your way through test chambers to collect them all!

Celeste-like movement added on top of current one (dash, wave dash, wallclimb and many more).
Certain test chambers were modified in order to fit into the gameplay, and to teach the mechanics.
125 unique collectable berries hidden all around the levels:
- Red Berries - difficult to find or difficult to get... sometimes both, sometimes none.
- Quantum Berries - they don't seem to like portals...
- Golden Berries - no.
Special ending allowing you to easily identify and collect the berries you missed.

It is recommended to know the source material (Celeste) before playing this mode.

Fog% (beta)

Put your muscle memory to the test. Can you run the game with limited sight?

Dense fog makes you unable to see distant areas.
If you don't move for 10 seconds, you can see through the fog until you move again.
Some say this mode will never exit beta testing...

Reverse Mod

Go back to sleep. You monster.

Start in Finale 4 and make your way back to Container Ride.
Un-solve puzzles along the way.

Odyssey Mod

Don't tell Nintendo.

Super Mario Odyssey movement added on top of Portal 2's movement.
Control objects at the drop of a hat.
Over 280 hidden Moons!

The Floor is Lava

Can you guess what this mode is about?

... and many more (in the future)

Stay tuned!

Troubleshooting

Keep in mind that this mod is a compilation of dirty hacks that this poor 2011 engine was not prepared for. In case the game crashes or bugs itself in an unexplainable way, try one of these things:

Make sure you've launched the main game at least once, then launch the mod.
(D3D error) Temporarily add -safe to the launch options in the mod's Steam properties.
(Manifest file error) Install the mod on the same drive as the main game, or edit the files.
If you are missing smsm.dll, you downloaded the mod from the wrong place. See the big blue button above?
Disable any other extensions (like SAR, for instance) because they might not like each other.
Update other extensions (like SAR), because they might be the one causing trouble.

Taking a hot bath and walking in fresh air for at least 30 minutes. (environment permitting)
Jumping from a ground-floor window.

If none of these things work, seek help in the P2SR Discord server, or make an issue.
