</>What does Game Speed do?

Game Speed lets you choose how fast Casualties: Unknown runs. Switch on Change Game Speed and set Game Speed Percent: 100 is normal, 50 is half speed and 300 is three times as fast. The setting replaces the game's normal speed only. The game's own speed buttons still give you their fast-forward speeds, time still races while you are knocked out, reading a note still slows things down and the pause menu still stops the game. When the game goes back to normal speed, your speed comes back with it, and the speed readout on the screen shows it, for example x1.5. Everything that runs on game time follows your setting, the layer timer included: at 200% hunger, thirst, healing and the time before the radiation line arrives all pass twice as fast in real time. The game stays at normal speed in the tutorial and the basic course, during cutscenes, on the death screen and in the one area where the game itself turns its speed buttons off. Nothing is written to your save, and switching it off puts normal speed back.

</>What is Game Speed?

This mod changes the normal game speed in Casualties: Unknown. Set Game Speed Percent high to get through long climbs and digging faster, or lower it to take hard fights and careful healing slowly. Normal speed comes back when you switch it off.

</>Common questions about Game Speed

Do the game's own fast-forward buttons still work?

Yes. Game Speed only changes the game's normal speed. The speed buttons still switch to the game's own fast-forward speeds, time still races while you are knocked out, reading a note still slows things down and the pause menu still stops everything. The mod steps aside for each of those, and as soon as the game returns to normal speed, for example when you press the first speed button or start walking, your chosen speed comes back on its own.

Does the layer timer run faster too?

Yes. The layer timer counts game time, so at 200% the radiation line arrives in half the real time it normally takes. Hunger, thirst and healing follow the same speed, so nothing gets harder or easier per minute of game time.

Does it change my save?

No. The game speed is not part of the save, and the mod writes nothing to it. Switching it off or quitting to the main menu puts the game back at its normal speed, and your runs, characters and progress stay exactly as the game saved them.

Why is the tutorial at normal speed?

The basic course waits for you to press the game's own fast-forward button before it moves on. A faster normal speed would skip that lesson, so the mod keeps the tutorial, the basic course, cutscenes and the death screen at the game's normal speed.

What options does Game Speed include?
