Finish Splinter Cell: Double Agent

Sam Fisher in the dark with three green lights; the stealth game at its most systemic.

Sam Fisher in 2002, with light and shadow as the whole mechanic.

The last Splinter Cell, and the one that let you play it loud.

Sam Fisher in Indonesia and Paris, and the asymmetric spies-versus-mercenaries multiplayer nothing has matched since.

Mark and execute, interrogations in real rooms, and objectives projected onto the walls.

Ezio Auditore in Renaissance Florence and Venice; the game that made the series.

Ezio in Rome, an assassin guild and the first multiplayer; the tightest Assassin's Creed.

Hack San Francisco with DedSec; the sequel that found the fun.
