WALKTHROUGH · Mission 11 OF 11

Checkmate

Mission 11 of 11

The climactic assault to end Pantheon, ending with the Black Sea showdown.
Setting: The Rook, Burgas Province, Bulgaria · 16 February 1991

Twelve weapons, and the base is full of them

The challenge here is Fatal Variety: get a kill with twelve different weapons. A defence mission is the right place for it — there are dropped guns everywhere — but only if you keep swapping instead of settling into the one you like. Pick up what the last one dropped, get a kill, move on.

How this one works

The last mission, and it runs at the same time as Separation Anxiety: one story in two places. Here you are defending The Rook — the safehouse — against a Pantheon assault, and the second objective is that Harrow does not get out.

The frame is an interrogation: Harrow has been unmasked as the CIA mole. Woods stays with her — he is in a wheelchair and is not going anywhere — and keeps questioning her while Marshall, Case, Adler, Sev and Felix hold the building.

The defence runs in stages rather than a flat wave count: an opening assault, then a trip to the shed for sentry turrets that triggers a second wave, then two Juggernauts to bring down, and a third Pantheon assault on the front yard to close it out. Along the way an APC shows up — destroy it with an RC-XD instead of gunfire and you get David vs Goliath as well, with two RC-XDs to attempt it and a checkpoint if the first one goes wrong.

What finishing it gives you

  • Fatal Variety — the challenge: a kill with twelve different weapons, only obtainable while playing as Case.
  • David vs Goliath — destroy the APC with an RC-XD instead of shooting it down.
  • Buried at Sea — for completing this mission, Checkmate, on any difficulty.
  • Case Closed — for completing the whole campaign, which this mission ends.

Still to verify

Cross-checked on 5 September 2026 against Game8’s mission record and a synthesis drawn from Deltia’s Gaming and thefilibusterblog — which agree on the location and date caption above, on the staged wave structure (opening wave, sentries, second wave, two Juggernauts, third assault), and that Buried at Sea is Checkmate’s own completion trophy while Case Closed is the whole-campaign one. What is still unverified is whether twelve distinct weapons are reliably available inside The Rook for Fatal Variety — no source addresses it either way, and that is the only thing reading cannot settle regardless — nobody here has played it.
