7. Escaping The Water Slums - Jak II: Renegade
Hands down, I'll fly Jak II's flag as the best open-world game since GTA III, but man, the mission where you've got to retrieve the Seal of Mar - only to then go up against an infinitely-spawning amount of soldiers - remains one of the hardest sequences Naughty Dog have ever put together across all their games. Respawning enemies are a big game design no-go, but a ton of old games used to do it as a way of forcing an intense situation, your character finding the resolve to battle through and escape their predicament, rather than staying to fight everything. In Jak II, the Krimzon Guard wouldn't only be blasting you with pinpoint accuracy from all directions at once (locking you in reaction animations that looped until you died), but they'd be swarming the skies in Hellcat Cruisers, preventing a vehicular escape unless you could bob n' weave your way through. https://www.youtube.com/watch?v=xLG69D912vQ Combine the lot and you've got a third-person shooter that didn't have a cover mechanic or even an aiming button, meaning you just had to dodge-roll and jump your way to freedom, hoping the game's code didn't trigger too many automatic enemy hits along the way.
