Advanced Coop Tactics

Description
Remake of DrFauli's map (Accelerated thinking) with some extra challenges. This puzzle requires no glitches, deaths, timing, ninja tricks, hidden elements, esoteric techniques or any such gimmicks. It is solvable using only simple moves that even a beginner would know.

The solution requires thinking fully ahead and playing accurate moves with little room for error. A single wrong move could set you back significantly or even require starting over. There are four designated checkpoints to track progress, each marked by a specific combination of player and cube positions. You will be notified when a checkpoint is cleared. You can then use the ping tool at anytime to reset to the latest checkpoint. Resetting will restore player and cube positions but fizzle all portals although they can be easily recovered. It is recommended to fully plan out your moves between checkpoints as any wrong move could require a reset. Checkpoints are optional and may be bypassed at the risk of losing more progress due to mistakes. If you are a purist and do not want to be spoiled of these intermediate states, there is a button in the spawn room that will turn off the checkpoint system entirely.

Checkpoint 1 - Both players in the laser room. Reflector cube on ⨉ button. Weighted cube on ▼ button.
Checkpoint 2 - Any player in the laser room. Reflector cube on ▼ button. Weighted cube on ~ button.
Checkpoint 3 - Both players in the laser room. Reflector cube on ~ button. Weighted cube on laser button.
Checkpoint 4 - Both players in the laser room. Reflector cube on ~ button. Weighted cube on ▼ button.

Difficulty: Very Hard (Not recommended for casual players)

You know that the map isn't easy when it takes you 90 minutes alone to figure out again how to get to checkpoint 3 - and finally we did it! Thank you for this map!

We just beat this map.
It took us about 3 Weekends and in total more than 24 h of banging our heads against the wall.
Awesome map! We loved it... and hated it... and now love it.
Thanks for sharing!

I now consider myself an advanced Portal Coop Player ;D

It took us about 3 days to completely solve it. Now we are confident that we have mastered the quantum physics from Harvard.

We gave up and followed the video. Still confused! We thought it looked familiar but didn't realize it was a Dr. Fauli map until seeing the description. No wonder it was so hard!

@Flush, Unfortunately I haven't figured out how to save progress across sessions.
