Editing Reverse MvM Beginners Guide (section)

=== Maps ===
While the majority of existing mvm maps are suitable, longer and more complex maps are best for reverse.  Bigrock, Mannhattan, and Rottenburg are examples of valve maps where it is relatively easy to stop players from getting to the hatch quickly, due to their layouts and/or overall length.  Shorter and more open-ended maps such as Decoy, Mannworks, and Coaltown, are still completely valid options, however they will require ample counter-measures to avoid players bypassing every threat and camping at the hatch.

==== Gate Maps ====
Maps with gates are very useful for structuring your waves at the cost of simplicity.  You can enable/disable bot spawns and connect your own custom logic to the outputs of the maps [https://developer.valvesoftware.com/wiki/Trigger_timer_door trigger_timer_door] entity using AddOutput, giving you the option to add rewards or enable new mission mechanics when capturing a gate.

==== Engineer Teleporter Types ====
There are 2 separate types of engineer teleporters: regular teleporters, and bot-style teleporters. Engineer bot teleporters act as a new spawn point, and will instantly teleport players to an exit on respawn with no entrance required.  It is recommended to only use bot-style teleporters in long maps that do not use gates, combining gates with this feature can confuse newer players.
