Balance and polishing.

[list] [*] Some elements of the second level (bridge detonation) were changed. [*]The Bastion mission is now swapped with the South Station mission, I see that most players play the missions in the order they are presented on the map, and this mission is more spectacular and easier. [*]Improved interaction with ladders, and fixed some bugs in interaction with ladders. [*]Improved the effect of the SSAO and SSGI post-effect (not so dark). [*]At Elysium III level, the bonfire will not work as a respawn point (as an exception, due to the presence of moving platforms). [*]The Olympic rifle in harpy mode now fires hybrid bullets like a rifle by holding the button instead of pressing it. [*]The firing rhythm quest module now also affects the machine gun in Harpy mode. [*]Turret loot chance increased from 60% to 80%. [*]The loot indicator now flashes more frequently and more clearly. [*]Fixed some system errors. [/list]
