Learn the Spike
Everything you need to nail a last-second defuse - the numbers, the rhythm, and the one rule that decides every clutch.
The one rule
A full defuse takes 7 seconds. So to defuse at the very last instant, you must start the defuse with exactly 7s left. Start earlier and you're safe but predictable; start later and it detonates in your hands. Everything else here is just learning to feel where that 7s mark is.
Read the final count
Easy mode colors the last 10 seconds like a traffic light, so the safe window is obvious at a glance:
The half-defuse trick
Defuse for just 3.5s and the spike banks a checkpoint: the outer casing drops halfway, the defuse tone pitches up, and that progress is saved. Let go and the spike does not reset to zero - you (or a teammate) can resume from halfway with only 3.5s left to finish. It is the basis of relay defuses and baiting out attackers. In the Trainer you will see a HALF SAVED flash the moment it banks.
The beep cadence
The spike beeps faster as it gets closer to going off. Those phases are your clock:
The 1-2-3-4 counting trick
In the final ~10 seconds the beeps come fast and even. Count them in groups of four - "1-2-3-4, 1-2-3-4…" - like a metronome. With practice you'll know, without looking, exactly which count lands on the 7s mark. The instant that beat hits, you start the defuse. That's the whole skill: turning a panicked guess into a rhythm you already know.
Drill the rhythm →See & hear the real thing
A full plant-to-detonation cycle for reference. Our trainer plays the real spike recording, so the rhythm you drill here is the rhythm you'll hear in game.
