OVERVIEW
Fuses are 2XKO’s team-identity system: after locking your duo, you pick a Fuse that changes how your two champions work together. Same duo, different Fuse = completely different team.
Your Fuse choice matters as much as your character choices — it decides your combo structure, your defense options, and your win condition.
Tip
New players: start on Sidekick. It simplifies the tag system while you learn your point character, and you can graduate to Freestyle later without relearning your champion.
EVERY FUSE EXPLAINED
The five Fuses, and who they’re for:
- Sidekick — your assist can’t be KO’d or tagged in; you pilot one champion with support tools. Best for: beginners.
- 2X Assist — multiple assist actions per sequence; your partner is constantly on screen helping. Best for: pressure-heavy duos.
- Freestyle — Handshake Tag twice in one sequence for extended team combos. Best for: combo creativity, high APM.
- Double Down — combine your Super with your assist’s for massive cash-out damage. Best for: damage maximalists.
- Juggernaut — fight as ONE empowered champion, no partner. Best for: pure solo fundamentals.

HOW TO PICK YOURS
Match the Fuse to your duo’s game plan, not the other way around:
- Setup characters (Illaoi, Caitlyn, Teemo) love 2X Assist — more screen coverage
- Touch-of-death duos (Akali, Yasuo) want Freestyle extensions
- Grapplers with super-heavy damage cash out with Double Down
- Learning a new character? Drop to Sidekick for 20 matches
READING THE FUSE MATCHUP
Your Fuse isn’t chosen in a vacuum — half the mind game is recognizing what the other team picked and adjusting your plan around it:
- Against 2X Assist — expect constant assist coverage; bait the partner out, then punish the recovery window while it’s off screen.
- Against Freestyle — one touch can go the distance, so respect neutral and don’t gamble on risky close-range buttons.
- Against Double Down — their damage spikes when both Supers are stocked; pressure their meter and force an early cash-out before it’s loaded.
- Against Juggernaut — there’s no partner to KO, but also no assist to bail them out; open them up once and the round ends fast.
You keep your Fuse all match, so the real skill is building your whole game plan around the strengths yours gives you — and the holes theirs leaves open.
