Here's a comparison of a normal chain grab strat VS a chain skip +big boost to lever (before the fake sister / box factory section).

NOTE 1: reaching the lever much sooner doesn't seem to skip the rotation of the level, thus making the skip much less significant (only ~1sec time save).

NOTE 2: pls ignore the mishap at the end ... got distracted having to stop the timer at the ledge grab after the box push :(

Here's a comparison of a normal jumping strat and an optimized boost using the slopes - before grabbing the mosquito leg.

NOTE: even if you don't get the big boost (like the one shown in the video), landing a bit on the left and having to do an extra hop /push right is still faster than the normal jumping strat.

NOTE: this strat applies only for XBox360 version of Limbo

When doing a 20 or 21 eggs run (XBox360 exclusive) and missing the worm turn skip (before Egg04), it is faster to push the box much farther left, before climbing it to get the worm out ... this is to avoing having to come back and go on the right of the box (as done in the usual strat) ... and it's a 3-4 seconds time save (see both starts in the video bellow).

This is a video comparions of 3 different strats for the boxes & button (in the Tire Factory). Using my NEW strat, you can save up to 1.5 seconds over the old strat. See the full breakdown at the end of the video.

Test 1 : Box Push (old strat) Test 2 : Box Climb (current strat) Test 3 : NEW STRAT (by yours trully ^^)

Not sure how many of you are aware of this, but there is a way to skip ~1sec at the start of the run, before even taking the first jump ... more surprisingly, it's within the rules :O Let me explain :D Depending on where you start the timer (which, for me, is also the first input that takes me ingame) it's possible to reach the ingame much sooner by pressing a key just as the loading is over, but NOT after the title screen is fully visible. Having as little of the title screen visible will make the game fade-out faster, because the title scren wasn't fully faded-in yet, therefor you reach the ingame right away - and, since the title screen comes right after the loading screen, this is still (kinda) within the rules ("Start the timer when press a Button on the title screen")

But, I don't mean to say we should definitely allow this ... mainly because it's kinda hard to tell what's going on in that load-to-title transition

A - a possible solution would be to start the timer when starting to load the first chapter (it's much more clearer when the red little square from the menu starts the blink) ... and you can spam any key to skip the title screen after loading, whcih would take you ingame right after the loading screen ... I timed this and it's very similar with the normal way ppl have been starting the timer (the difference is ~0.1sec, which means all times from the LB can stay the same, only the rules have to be tweaked a little);

B - another (much simpler) solution is to simply adjust the rules to say that the title screen has to be fully visible before starting the timer / the run;

C - but, on the other hand, anything can reamain the same, and the title-skip could be allowed ... the ~1sec skip at the start would be pretty sweet imo.

@all mods, let me know what you think.

video proof : A time comparison between 3 ways to start the run (3 attemtps for each of the 3 strats): 1 - start the timer when loading the chapter. and spam any key to skip the title screen. 2 - start the timer when pressing any key while the title screen is fully visible. 3 - start the timer right after the loading is over, before the title screen is fully vissible.

With the recent discoveries, we now can gain at least 6 seconds in the Mine - and, by doing so, we can skip 1 shockwave cycle. Here's the video to prove it \o/

the skips and tricks used in the optimized segment are:

• side bounce from door hit + quick recovery
• beach landing the submersible
• 1 breath swim
• minimal swings on ropes
• facing the freaks #1
• top ladder early jump
• minimal crank turns
• facing the freaks #2
• mounting the jetbox
• stumble glitch
• instant recovery from door stun

I'm not fully convinced the stumble glitch is absolutely necessary. you can see the fully optimized run reaching the block a bit sooner, even pausing for ~1sec before the blast hits.

(check the video playlist for the full list of Inside skips : https://www.youtube.com/playlist?list=PLpJA1uAgx2cXg4fjHGK9yBQfKfdMWJmUz )

Finally I managed to show that this skip is possible \o/

In the video you can see my Trials and Tribulations to get the Double Button Door SKIP using the SUPERBOOST. I hope the video does justice to the risks involved and how difficult the skip is. Each successful superboost had countless fails and resets, but it was all worth it.

See for yourself at the end of the video \o/

(these strats apply only for XBox360 version of Limbo)

To get the Egg15 you have to switch the boxes, to get the correct box at the guns ... in these 2 videos you can see how to optimize the box switch - to get faster to the guns

Note 1: check the video descriptions for explanations about the movement and precise steps

Note 2: the gun cycle lasts ~13seconds . therefor reaching it sooner is a big time save

Note 3 : it is possible to reach an earlier gun cycle, using the "gap" strat (above) and getting carried up the slope by the box - thus not needing the second gravity switch, since you can already push the box to the gun ... but it's risky and hard to pull off

(this strat applies only for XBox360 version of Limbo)

Doing a death warp at the Egg4 (XBox360 version) saves 3 seconds compared to the normal route ... you can see a time comparison in this video :

This is the YoYo Elevator trick - to get the necessary freaks to glitch out. The video shows a time comparison between the YoYo Elevator Glitch against the normal way (saves at least 3 seconds, if done properly). Big thanks to Lightdrew, for helping me optimize the movement to get more consistent results.

This is the elevator optimization for Egg 4 Urban Exploration. It saves 2-3 seconds from the usual elevator movement. Note: it might work with swag elevator as well ...
