This trainer is not meant as a cheat tool, which takes away any and every challenge, but rather as a subtle assistant, which helps flattening the learning curve when familiarizing yourself with the game.
The "philosophy" behind this trainer is that many of the challenges that new players face are actually absent for experienced players — and not just because they have become "better"... Once you've played for a while, you will have all the keys, know all the exits, loot and NPC locations, so, despite these challenges being gone, it's still a fun game, so I'm trying to make a new player enjoy the game similar to how a more experienced one would. As far as NPC indicators are concerned - I find that, if you have no enemy Intel whatsoever, you can only play the game as a twitch shooter: Run around as quickly as you can, and hope that you will shoot faster if you run into an enemy... (Not my kind of fun.) But once you have at least some vague idea of where enemies are, you can then try to sneak around them, or up to them, and generally have a plan. (Much more interesting, at least to me.) So that's why I implemented those indicator bars that simulate somewhat what you might sense via very sensitive hearing.
The trainer has the following features:
Indicate Exfil points A marker is shown at the top of the screen, pointing in the direction of the available Exfils.
HUD A HUD at the bottom of the screen shows ammo counts, firing mode, and compass direction.
Indicate loot Lootable containers, caches & loose loot are shown via an icon. For containers & stand-alone items you have to be fairly close for them to show up (e.g. in the same room); caches are shown within 100m. A search list can be defined, and if an item in that list is found, the icon will indicate this.
Thermal vision & Night vision Use night/thermal vision, even if you don't have the required equipment in your inventory.
Unlock doors All doors are unlocked when the mission starts.
Open door without looking Pressing a hotkey will open the nearby door, even if you look in a different direction.
Indicate NPCs NPCs that are within detection range are indicated via a bar at the top of the screen. The closer the NPC gets the more accurate this indicator will become. If the NPC is seen, the bar's color will show his side. If he's fairly close his relative elevation is indicated as well. If the NPC is standing still, the bar will disappear. If he fires a shot, the bar will briefly turn red.
