Ignore Personal Top 3, can't change title. **Note: Current Room Gen refers to room gen prior to 1.2.8 Alright, I'll start this off with this. I selected the earliest version that has hotkeying to my knowledge. There might've been a version prior but as far as I know this is the earliest one.

Version 1.2.0 Version 1.2.0 is - as far as I know - the earliest version that contains hotkeying. Hotkeying is a key factor because prior to this, it's just base containment breach with jumping and practically always safe (in terms of handling deaths). Pros: • Practically Instant Respawning • Papers don't lag you (if you accidentally open or need 372) I think that's it. Cons: • 173 appears to like to spawn in the hallway just before 914 on 446. • 446 seed is different after containing 008, getting l4 and l5. Wow... I found the 446 error mid-run • No 100% What categories could you run a possible wr in with this?

• All 1 player categories EXCEPT for 100%.

Version 1.2.3 Version 1.2.3 is currently the oldest version on steam with the current map gen. Something must've happened to older versions that also had the current map gen as those versions no longer have the current map gen. (Thanks Cookie!) Pros: • Instant Respawning • Documents don't lag • Room Gen is current room gen (perfect for speedrunning set seed) • 173 does not spawn in the hallway before 914 on 446 • Most ideal version for a solo 100% run Cons: • No dupe bug :( What categories could you run a possible wr in with this?

• All solo categories
• Multiplayer categories w/o using glitches (e.g. 1.2.7 dupe)
• 100%, our best friend

Version 1.2.6 The one I feel like a lot of us are used to. Fun Fact: this is the version the first 914 4+ run was done on. Pros: • Rather the opposite of 1.2.0's cons, 173 does not tend to spawn in the hallway before 914 on 446. I don't believe I can find any major positive difference between 1.2.6 and 1.2.0. Cons: • Death screen has a slight delay. I would think that's it, someone probably has gone a bit more in depth, I'm just doing some basic coverage. What categories could you run a possible wr in with this? Once again, probably every 1-player category set seed category.

Version 1.2.7: The current version, and probably should be rightfully called Version Dupe.7.

Pros: • Dupe. Just, dupe. • Makes 2+ player runs a LOT quicker. • Duping at the start doesn't add to time as you have not made a camera or player movement. • 100% runs became hella lot more easier. Cons: • Theres a loading screen. Why? Just, why? • Would not be ideal for anything but 100% or set seed (both 2+ players.) Version Dupe.7 is a meh update. The bugs outweigh the loading screens in most cases. What categories could you possibly set a WR in? • 2+ Players 100% Set or Random Seed. • Set Seed 2+ Players

Version 1.2.8: Current version as of now. Pros: • 106 room is reverted to normal. • Basically yeeted an indev patch for base cb, so likely will have similar room gen • Orientation of rooms could speed up runs (e.g. 446456054 start) Cons: • No more dupe bug D; • Orientation of rooms could also mess up runs (e.g. surveillance in 446456054, small time loss but slightly made up by the former pro) • Can sometimes not load rooms properly after death (

I believe that's about it for now. Recap: Most Categories for 1 player: 1.2.0 All Categories for 1 player including 100%: 1.2.3 Random% Categories 1 player: 1.2.6 or 1.2.3 All 2+ player categories: 1.2.7 or 1.2.3 (if glitchless run) Maybe glitchless 2+ player categories: 1.2.8 as its getting close to base cb room gen.

I just found out that on 446456054 on version 1.2.9.3 173 will spawn in the corridor before 914. 1.2.9.3 doesn't seem played enough to warrant any consideration to being added to the main post.
