Rift Incompatible

Missable, and the classic trap: during the side mission "Exit Through the Rift Shop" you must punch (melee) Francis Oddman, not shoot him, to send him through the rift - shooting him locks the achievement for that character. His frozen body then shows up in Terminus Range (Windspear). Melee only. Recoverable via post-story New Game+ or co-op if you slip. The game's other missable is All Things Vend.
