In-game time: 8:19
A serious mistake at the end wasted several seconds - the Spy needed to be ordered to go towards the plane first, then call the radio. There's a potentially big improvement - you don't have to use the Balloon to get the Clue, then the bunch of soldiers guarding it may be left alone. It would probably change the overall route a lot though.
Rules:
- In-game time is the only goal. Inventories, objectives list and pause don't waste time.
- All bonus books.
- All objectives - Secondary and Clues. Since the mission result screen doesn't keep track of Clues, objectives list must be open during the mission to showcase all Clues as completed.
- Not being detected and not being injured, the former means that must not be fully seen by the enemies at any point (even unarmed ones and snipers), but blue-red flashing is allowed.
- No alarm. Events that normally raise the alarm are allowed in alarm-insensitive areas. If explosions are required by the objectives, they're allowed at the end of the mission (within last minute).
- No shooting enemies, except for using the sniper rifle. Also, the default pistol is allowed for distracting the enemies.
- No Ctrl glitch (harpoon on land, Natasha's undetectable sniper rifle), no Syringe glitch (affecting an enemy far away).
