Victory Conditions

Victory Conditions are a Mechanic in SCP: Secret Laboratory that determines when a round will end and which team will be decided as the winner.
Currently, a round will only end under the following three conditions:

• Only MTF and Scientists are left alive.
• Only Chaos (25% or less) and SCPs are left alive.
• Only Chaos and Class-D are left alive.

After one of the following three conditions are checked, the winner will be decided based on three factors: The amount of Class-D Escapes, Scientist Escapes, and SCPs still alive. SCP-049-2 instances are not counted as SCPs still alive despite the fact they affect the "number of terminated SCPs" on the round end screen.
Class-Ds or Scientists that escaped while disarmed will NOT be counted towards the amount of Class-D Escapes or Scientist Escapes, despite the fact they will respawn as the opposite team. So while MTF escorting a disarmed Class-D to the escape area will not give them points towards winning, it does prevent the Class-D from being used towards an Insurgency victory, while also giving the MTF an extra teammate.

Conditions Table

Who is left?	Who Wins?
Only MTF and Scientist left	If Scientist Escape is higher than Class-D Escape- Foundation Win (Tie Breaker)
	If Class-D Escape is higher than Scientist Escape- Stalemate
Only SCPs (25% of Chaos are alive)	If Scientist Escape is higher than Class-D Escape and alive SCPs - Stalemate
	If more SCPs are alive than both civilian escapes- SCP Win (Tie Breaker)
	If Class-D Escape is higher than Scientist Escape and alive SCPs- Insurgency Win
Only Chaos and Class-Ds left	If Scientist Escape is higher than Class-D Escape- Stalemate
	If Class-D Escape is higher than Scientist Escape- Insurgency Win (Tie Breaker)

End Screen

Upon the round ending, the End Screen will appear on all player's screens, displaying what team won or stalemate. Each of these have a unique message relating to the team that won.
If the Foundation wins: "All threats to safety have been neutralized. Site-02 is secure once again."

If the Insurgency wins: "Foundation presence has been exterminated. Operatives standing by for further orders."

If the SCPs win: "The escaped subjects have overrun the facility. Emergency response has been scrambled."

If the round ends in a Stalemate: "Site-02 is under certain control, but not without cost. The victor is undetermined."

Additionally, the lower part of the screen will display the following information:

• One of the following two messages are displayed based on the status of the Alpha Warhead.
  • "The Alpha Warhead was not detonated during this mission."
  • "The Alpha Warhead's detonation terminated X beings."
• X/Y Class-D escaped
  • Despite saying escaped, this counts both Class-Ds that escaped and any Class-Ds that are alive at the end of the round.
• X/Y Scientist(s) survived
  • Despite saying survived, this counts both Scientist that escaped and any Scientist that are alive at the end of the round.
• X/Y terminated SCPs.
  • The Y value will increase by one for each SCP-049-2 instance created in the round, despite this, these instances do not affect the winner of the round, even if their termination is required.
• The mission took X minutes and Y seconds.
• Next round in X seconds.
• The SCPs killed X human beings.

Trivia

• In earlier versions of the game, the team that won at the end of a round was Class-D and MTF instead of Insurgency and Foundation.
• Previously, all it took was one Class-D escaping for the Chaos Insurgency to meet their win conditions.
  • One Class-D escaping made it no longer possible for SCPs or the Foundation to win. Making it only possible for the round to end in a Stalemate or Class-D Win.
    • Even if the match ended with only SCPs left alive, it would still result in a Class-D Win.
• In older versions, SCPs could still win the game if all of them are killed. This was only possible if there are only Chaos and/or Class-Ds left alive and no Class-D escaped.
  • This made it possible for SCPs to win the game early on by simply killing all Facility Guard and Scientist, leaving only the Class-Ds left alive. Afterwards, all the SCPs could suicide via Tesla Gates or Bottomless Pits in HCZ. Forcing the round to end in an SCP Victory.
  • This was eventually made impossible when Victory Conditions were changed so Class-Ds that are alive at the end of the round count as having escaped.
• Before the Victory Condition Rework in v11.2.0, both disarmed Scientist and disarmed Class-Ds escaping would count towards Victory Conditions for the opposite team (i.e., disarmed Class-D counted towards MTF Win while disarmed Scientist counted towards Insurgency Win).
  • This feature was originally a fairly popular plugin that became base game in the Megapatch II (v9.0.0) update.
