The hardest Assassin’s Tomb in AC2 is commonly considered San Marco’s Secret in Venice , in the northeast corner of the city map. It’s the one many players describe as the most annoying because of the longer parkour route and trickier platforming.

Tomb location

  • Name: San Marco’s Secret.
  • City: Venice.
  • Where in Venice: Near the northeast corner , with access up onto the roofs and beams before you can drop into the tomb entrance.

Why people call it hardest

  • The route into it is longer and more vertical than many other tombs.
  • It has more awkward climbing and beam navigation, so it tends to trip people up even when the actual combat is not the issue.
  • Some players instead call a different tomb hardest, but San Marco’s Secret is the most common answer in guides and discussion.
