Hello! due to glitches that have been found (or ones on new engine that can be adapted to work on OE) I feel the need for a post to be made documenting all of the tricks and shit for OE for possible use in a Rerun This will be updated if any are found (not alot at the moment but things like the d2\_coast\_03 skip are doable in OE) [c17\_06a skip](https://www.youtube.com/watch?v=_i0AK2sovv4/) [trainstation\_01 gate jump](https://dl.dropboxusercontent.com/u/25190969/HL/gatejump.mp4/) [d1\_trainstation\_06 triggerdelay](http://puu.sh/bzbMq/b49256917b.webm/) NOTE: might not be usable due to all weapons being invisible forever [canals\_03 skip](https://www.youtube.com/watch?v=ZjGf1yfwHjk/) [possible train skip](https://www.youtube.com/watch?v=OKcQQd7_5c4/) [c17\_10a triggerdelay](http://www.youtube.com/watch?v=bPECDWkq7Ec/) [prison oob stuff](https://www.youtube.com/watch?v=94PLqo7lSKI/) [SPT for old Engine](https://github.com/YaLTeR/SourcePauseTool/releases/tag/v0.7-beta1/) Commands to remove jitter: cl\_interp .0015 (note things like elevator doors will be glitchy) cl\_interp\_npcs .1 (prevents NPC’s from looking like shite) [shadow=red,left]PHASE 2[/shadow] ---

Good idea, I’ll start looking for some trickjumps that can possibly save time. ---

I’ll try and help you guys route and maybe with the run. Also I’d suggest doing the run on Easy for some sexy ass damage boosts. Also Yalter made a autohop dll’s for OE. Just replace your current bin folder in your /hl2 folder with this: [https://www.dropbox.com/s/77xustqoviejo72/bin.rar?dl=0](https://www.dropbox.com/s/77xustqoviejo72/bin.rar?dl=0) ---

There’s some places in prison where you can go oob and potentially save a lot of time and if we had autopausing getting back inbounds would be super easy. ---

Yeah, running on Easy is always faster in Source runs as you can fit in more damage boosts in 100/100 hpap ---

> [@Elgu](#): > > how does auto pausing help? Since you go upwards when save/loading you have to go back inbounds from below the map which also means your save/loads will have to fight with gravity so autopausing would make it a lot easier to minimize the effects of gravity. ---

There’s also [this](http://www.twitch.tv/maxxuss/c/3696412?t=1m35s). Not sure if that only works in new engine, but it’s worth trying. You can maybe do a ceiling clip in trainstation\_03 according to [this thread](https://forums.sourceruns.org/index.php?topic=178.0). ---

If done on easy you could make use of grenade launches a lot, kinda like GoldSrc style, but in the HL2. It’s probably not necessary on these parts of Coast, they’re just examples. [Next page](https://forums.sourceruns.org/t/half-life-2-old-engine-rerun/2457.md?page=2)
