Question 1

What is IGT (In-Game Time)?

Accepted Answer

Timing method that uses the game's own internal timer, which typically pauses during loads, menus, and cutscenes. Fairer across different hardware but not available in all games.

Question 2

What is RTA (Real-Time Attack)?

Accepted Answer

Timing method that measures wall-clock time from start to finish, including load screens, cutscenes, and menus. The most common timing method.

Question 3

What is Hard CC (Crowd Control)?

Accepted Answer

Effects that fully prevent the player from taking any action for a duration: stuns, freezes, petrification, knockdowns, sleep, and similar. In challenge run contexts, hard CC is typically treated the same as a hit because the player loses control involuntarily.

Question 4

What is Soft CC (Crowd Control)?

Accepted Answer

Effects that limit or impair the player's actions without fully disabling them: slows, blinds, aim disruption, silence (blocking abilities), and similar. Whether soft CC counts as a "hit" varies by game — check each game's rules page for specifics.

Question 5

What is Invincibility Frames (i-frames)?

Accepted Answer

A window of time during certain actions (dodges, rolls, backsteps) where the player cannot be hit. Understanding i-frame windows is critical for no-hit runs. Taking a hit during i-frames does not count as a hit.

Question 6

What is Self-Damage?

Accepted Answer

Health loss caused by the player's own actions: fall damage, explosive splash, poison from consumables, etc. Rules on self-damage vary significantly by game. Some "no-hit" rulesets exclude self-damage; others include it. Always check the game's specific rules.
