General routes are up to you to make, as a standard route can easily be broken due to SCP 106. If you want to find a better seed, be prepared to wait hours until you find one that includes everything needed for 100%. The seed for Pre v1.3.6 used on v1.3.3 took hours to find, only because the game would not spawn in things like the 'Butt Ghost' toilet, SCP 178, and even sometimes, SCP 079. In older versions of the game, there is a very high chance that a random seed will not spawn with everything needed in order to 100% the game. Please note that you do not have to use the recommended seed for either of the two categories. The seed that is encouraged for Pre v1.3.6 is '44y1', along with version 1.3.3. The seed that is encouraged for Post v1.3.9 is '2zf61th1', along with version 1.3.9.

Similar to the paragraph above, using a version other than v1.3.3 may result in the map being completely different than v1.3.3's map. You are also encouraged to use v1.3.3 for the Pre v1.3.6 category, as there is also a good seed for speedrunning. Note that if you use a different version, other than v1.3.9, the map might not be the same You are encouraged to use v1.3.9 for the Post v1.3.6 category, as we have found a pretty good seed for speedrunning. Runs done on v1.1 to v1.3.3 can be done on any difficulty. Runs done on v1.3.7 and above must be played on keter difficulty. This achievement was only added to the game in v1.3.7. The 100% category is split into two sub-categories because of the 'Survival in a Nightmare Achievement', which means to beat the game on keter difficulty. Versions 1.3.4, 1.3.5, and 1.3.6 are not allowed to be used in speedrunning this category, as there is an achievement in the game that is not unlockable due to a bug. Pre v1.3.6 means that runs are allowed to be done on versions 1.1 to 1.3.3. Post v1.3.6 means that runs are only allowed to be done on versions 1.3.7 to 1.3.11. In Pre v1.3.6 you should finish the game with 36/35 achievements unlocked.

In Post v1.3.6, you should finish the game with 37/36 achievements unlocked. To successfuly finish a run in either category, you must unlock every single achievement in the achievements menu in the pause screen. There are two different sub-categories for the 100% category. This is Part 3 (100%) of 3 guides for speedrunning Containment Breach. This guide is a work-in-progress and may or may not be updated as time passes on.
