Editing Biotics Lab (section)

== Map layout ==
The map is divided into three floors. The top floor, which is where the players start, is the largest of the three and contains the majority of the rooms, corridors, and item spawns. The middle floor, sometimes referred to as the second floor, is considerably smaller than the top floor, containing only four accessible rooms, three of which are interconnected in a 'U' shape off the corridor. The bottom floor is the smallest, with only one room that is accessible at all times.

=== Trader locations ===
There is a [[Trader|trader]] on each of the three floors. 

*The top floor [[Trader|trader]] is found on a direct route from the spawn point, with no doors between the two points. 
*The [[Trader|trader]] on the middle floor is inside one of the main defensive positions on the map&nbsp;– in the largest room of the floor, where partially dissected [[Clots]] are found. 
*The [[Trader|trader]] on the lowest floor is one of only two rooms on that floor, directly across from a barricaded corridor; a spawn point for the [[Specimens|specimens]].

=== Historic data ===
{{KF-mod notice|s}}
'''Biotics Lab''', as it appeared in the original [[Killing Floor (modification)|''Killing Floor'' mod]], was largely identical to its final form in the retail version. The main difference is improved graphics and additional [[Trader|traders]]; the original featured one [[Trader|trader]] found on the bottom floor. The top floor [[Trader|trader]] was originally the 'money room', which contained respawning riches and could only be accessed after unwelding the strong door at its entrance. The [[Trader|trader]] on the middle floor is a new addition for the retail version.

In the ''Killing Floor'' mod, the sections of the ventilation system in which [[Crawler|Crawlers]] and [[Stalker|Stalkers]] spawn were absent.  Several ammo and weapon drops were also absent, and others were moved to accommodate the blockades.  The various blockades in front of [[Specimens|specimen]] spawn points were instead invisible walls that only blocked the player's movement.
