A C130 Hercules carrying twenty crates of general cargo and five crates of top secret prototype weapons has crashed near the old British atomic testing range in South Australia. The region is huge but sparsely populated. Native villages, holiday resorts,opal-mining operations, military bases, abandoned industrial sites, radioactive anomalies, etc complicate Jack Carver's mission to recover the cargo.

Only editors I ever used were crytek sandbox, and the editor that was bundled with TombRaider Chronicles. Timed runs were a common feature of TR games. I can't recall too many in FarCry. There was the Landa Gas Room in catalyst Aftermath by SkRipT.
If there are any others, someone might tell me. Anyhoo, I have one here. Run, jump, solve puzzle, obstacles, crouch/prone, run some more. Twenty two seconds before the door slams shut again.
