1. Trigger Bypassing:
Many objects, doors, enemies, cameras etc. are primally activated, when the according trigger is triggered.
During playing, you usually can not cognize a trigger (except it concerns a trigger which is supposed to be recognized, by having a different texture) so they're often unconsiderately placed because the builder expects that the player goes the destined way (and e.g. does not jump above a slent, when he just can pass next to it) Therefor a picture of rr-carrols "Trigger Squares et al"-thread. The trigger (yellow) can be avoided by taking the unusual way.
But if you know where the triggers are placed, it is easy to avoid them. So you can for example avoid the past monster's which guards the citadel, appearance whereby there won't appear any locusts in the whole level anymore.
You can avoid many of the triggers by, as described above, taking an unusual way or jumping a "banana jump" around them. However mostly you have to use a special trick and jump, crawl or run through a solid corner.
2. Cornerbugs:
The propably most known trick in TR is the cornerbug whereby you can reach some higher seated platforms, by getting into a solid corner.
In TR2 and TR3, there are many possibilities to make the cornerbug. Who's interested in, can look them up here: http://tombrunner.net/area51.php#corner_bugs nachlesen.
In TR4, TR5 and therefore the LE as well, some are not possible any longer or they work very seldom.
a) Normal Corner Bug:
This bug works at the most corners but it's very difficult or sometimes even impossible, when the corner is walkable from all sides, like in the picture (it works in the pictured corner, but it only should be used when the Crawl Cornerbug (see b) doesn't work because this is the faster one).
The normal cornerbug only is useful when it has just one of the 2 sides that are walkable from the corner, like in the picture.
Now position Lara like in the picture and jump straight up.
Lara should be drawn into the collumn and finally land on it. If this does not happen, turn Lara to- (when Lara is pulled into the corner but then is pushed out again) or aways from the collum (when Lara just jumps straight up and nothing happens).
b) Crawl Cornerbug:
This bug works at mostly every corner ("mostly" because cornerbugs are under special conditions influenced by cardinal direction and the corner's position, so do not give up at once if it does not work, but try the bug from another side) but best at such like pictured in the first pictue at the "Normal Cornerbug").
Stand at the corner as shown in the picture
press and hold "crouch" (usually ".") and tip right after it shortly on "Forward". Lara should now crawling in the corner. Leave "crouch" now and you'll be "teleported" up. If Lara does not manage to get into the collumn, change the angle to the wall and/or move Lara closer to the corner.
c) Swim Cornerbug:
One of the most difficult cornerbugs, that only seems to be working on special cardinal directions (when the corner is directed to North-West). Position Lara like in the picture and press "jump".
Now Lara bathes down and is "teleported" up short after that.
If it does not work at once, there are the following methods: After diving press "Forward", after diving press "Backward", changing the space to the corner, changing the angle. When it doesn't work anyway, it is probable that the swim cornerbug does not work at the corner you are trying.
3. Advanced Rope Swinging
Basically the rope swinging is relative easy in TR4. You only have to angle the ropes that accurately that the second rope behind the one, Lara is dangling on, disappears and then you can jump across with a little startup.
In some Custom Levels, from time and time there are some really difficult rope swinging passages, so I decided to assemble it in my level.
a) The problem is:
After you took a run-up you do not get to the next rope, because Lara always bangs her head, whereby the jumping-distance is changed drastically. It does not help as well to jump off before you reached the highest point, because then Lara can't jump any further.
It seems that the red-marked part would make the jump impossible.
The solution: Jump off after you reached the highest point. The boost that Lara has by reaching the highest point is kept for a short time although Lara is already swinging back (see picture).
b) Actually, this case is all common, but I intigrated it into the level to complete the tutorial.
The problem is: As you learned in TR4, you arrange the ropes that the second rope disappears behind the first one. When you take a run-up, Lara does not swing as usual straight but she makes a little bend shortly before she reached the highest point.
The solution: Arranging Lara according to the bend. E.g. Lara makes a bend to the left, you'll have to arrange the rope like that that the rope which Lara is hanging on, on the right of the second rope is to see, where she's supposed to jump to. To find the perfect start-position, you'll have to experiment a little bit.
4. Rope Glitch
Discovered by xRikux89.
As great as this glitch is, it has no use in the original TR’s, since it only works if a rope is hanging directly above Lara and can be reached by jumping straight up. The only spot where this is possible is the “Tomb of Seth” in TR4 (See the picture)

Thank god it’s different in the Customlevelscene, as there are some levels with such a setting. Hopefully these lines won’t change that in the future, as this glitch brings a lot of fun!
If you want to do it you have to stand some centimeters IN FRONT OF the rope. Then simply jump up and press both “ctrl” and “Backwards”. As soon as Lara grasps the rope

let go off everything. If everthing worked Lara should now fly through the air at great speed.
This way Lara can pass huge pits with a lenght of at most 11 squares.
Special Tricks:
a) As Lara is flying at a great speed, she’ll get teleported up (similar to cornerbug) when colliding with a solid wall.
b) If there’s another platform above the rope you can use this trick to let you “draw” through the ceiling onto the platform. Just don’t let go off “ctrl” at first but wait until Lara is on the higher platform. It’s quite hard to find the right moment as you will bump into the ceiling, if you do it too early or fly through the air if you press “ctrl” for too long.
5. Advanced Jumping Technics
a) One-step-running-jump:
This trick is pretty common and extremely helpful if you try to jump from one triangular floortile to another one. Using this trick you will need half as much distance for running as you would need for a normal running jump.
To do this special jump start with a step forward. While Lara does this step let go off “walk” and press and hold “Jump” instead.
Sometimes this trick isn’t working properly and Lara keeps running without jumping. In my level this could happen too at the second “one-step-running-jump”. However if you jump back to the first crystal and do both jumps in one go, it should work.
b) The longest jump:
Sometimes a normal running jump won’t be enough to jump from one platform to another one. If this is the case and it seems that Lara should be able to do this jump try this:
Go to the edge, hop back and start running but this time press “jump” in the very last moment. Lara will jump off from the air and this way the jump will get her some centimeters farther.
If it still doesn’t work, pressing “forward” might do it!
c) Getting an extra-boost from a slope:
If you hit just a tiny part of the slope it will act like flat ground. You can use this to your advantage if you want to increase your jumping distance.
In my level you’ll have to use this trick so jump towards the highest point of the slope and press and hold forward. Lara will hit the slope and reach the next platform.
This trick also works if you hit the lateral edge of a slope.
6. Dive Bug
It was discovered by Aurelien in the TR2-level “40 fathoms” and optimized by rr-carrol.
Using this bug you can get down huge pits without losing health . Your objective is to do a swandive and reach the tiny sector where a wall meets a floortile. (Lara has to be able to stand on this floortile. It won’t work with slopes)
You should be able to align Lara to the “nearest millimetre” so here are some tips that might help. ("<" and ">" should tell you which one of the movements covers a bigger distance.

- Step forward < step backward
- Step forward WAIT Step forward > two consecutive steps forward
- Step forward WAIT Step forward < running forward a little bit (pressing (not holding) forward)
- Running forward a little bit < roll ~ hopping back
- Turning a tiny bit might help to increase the distance to the wall a little bit.

7. Timeruns
Of course a time run can’t be missing in my level and because it is a special kind of tutorial level you must fulfill some tricks to complete it in time. The time is limited in such a way that you are allowed to miss one trick.
a) Stumble Cancelling:
One of the most important tricks used in time runs. If Lara jumps to a much lower platform, she needs some time before getting back up, which costs a lot of precious time. The two most important Stumble Cancels are:

1. Flare Cancel: Take out a flare and jump down to the lower level. Shortly before arriving down throw the flare away (with “,“ key) then press and hold forward. Lara should now be able to run directly forward after reaching the ground. You should be able to control that trick perfectly because you need to use it two times.
2. Roll Cancel: A roll seems to be most of the times faster than the animation for getting back up. But if you have enough flares, you should use the flare cancel. But there is some special occasion for the roll cancel. When Lara has to land near an edge that is at least 2 clicks higher than the square in front of it, she will be able to perform an elegant roll into the pit so she can keep on running.

b) Jumping farther:
If Lara must reach a deeper level it can help to press the action key while you're in the air, because then Lara jumps a little bit farther.
With the help of the swan dive Lara gets as far as with the jump + action key.
c) Safety Drop Trick
You need this trick to get into the gap if two floor level are exactly under each other. For that place Lara with the back facing the edge and hit shortly the back key (an alternative way would be to place Lara with the face to the edge and the press the roll key). The time you are in the air just hit the action key very shortly, that will force Lara to stretch her hands out forward, but she won’t grap the edge.
d) The fastest way out of crawling spaces:
To drop down from crawling spaces there is no need to be precisely in an angle of 90° towards the edge. It is enough if you have a position like it is shown on the picture (around an angle of 45° degrees towards the edge) then just press the “back” key + “action” key.
Speaking of crawl spaces: Don’t forget that you can perform a crawling roll (“Sprint/Dash” + “Duck” key) in this level.
e) Passing on from sprinting into another movement

- You should already know that Lara performs an elegant roll if you press “duck” key during sprinting.
- Should also be already known, but has a nice second effect: If you sprint and then you press the jump key Lara will make a dive roll. If you will make this dive roll near an edge Lara will gain extra boost on the following fall. That is especially helpful if the ceiling is so deep down that Lara won’t get far with a normal jump from running.
