Fixes:

- Metro for Regular Wave Set not working (enemies do not spawn).

- Character outlines re-enabled for Isometric mode, but kept disabled for First/Third Person modes;
- Low health red screen effect re-enabled/fixed.

Department:
- File size optimizations;
- ISIS flags for ISIS waves;

Truckstop:
- Map structural changes (inner walls removed, so when you blow em all up, you can go through them with no issues);
- Navigational changes (to prevent enemies getting stuck at sandbags, not thoroughly tested);
- ISIS flags and Burning City background for ISIS waves;

General changes:
- Civilian/enemy outlines removed;
- Minimap is visible at all times;
- New playable character: Redhead (Craxi, Dante and Shadow not added YET);
- Slight change to Metal music set;
- Custom Weapon added: Saiga-12 fully automatic shotgun. She weights 3.6 kilograms and fires 12-gauge buckshot at 600 rounds per minute. To access it, spawn it via the cheats menu (same as M240B handheld);
- Reworked Default and ISIS wave sets, as well as additions of Desert Eagle wielding enemies for more variety;
- Color variations for ISIS enemies;
- Reworked Main Menu visuals: Notim Portant replaced by Psycho Cop, Pistol with Desert Eagle, lighting changes;
