SublevelEscape

This update adds deeper tactical choices and more rewarding replayability. - Added a new 10,000-point scoring and grade system with different priorities for each mission type. - Escape, elimination, keycard recovery, timed, and survival missions now evaluate stealth, accuracy, alert control, speed, and evasive play differently. - Rising alert levels now trigger active searches and reinforcements including guards, drones, and heavy units. - High alert can lock down the exit until security pressure is reduced. - Reworked SCAN with three selectable modes: Structure, Threats, and Supplies. - Expanded EMG into a tactical ability that tags up to three threats, interrupts attacks, and exposes enemy weak points. - Added security terminals and explosive bio tanks to the Bio Lab. Terminals reduce alert, while tank explosions can damage both enemies and the player. - Added distinct WARDEN-0 boss patterns including burst fire, charges, and area shockwaves across its combat phases. - Updated optional objectives and mission results to support more varied strategies and grade challenges. - Added controller support for switching between SCAN modes. - Rebalanced SCAN resources and EMG charging to make exploration, combat, and successful evasion more meaningful.
