OVERVIEW
The Tag button is the most important button in 2XKO — and the most misused. Assists, swaps, and Handshake Tags are three different tools sharing one button, and knowing which one a moment calls for is what separates duos from two solo players sharing a screen.
Tip
If you only use Tag when you’re in trouble, your opponent already knows your pattern. The best tags are the boring ones — mid-pressure, mid-combo, planned in advance.
THE THREE TAG ACTIONS
One button, three tools:
- Assist (tap) — partner attacks and leaves. Covers your approach, extends combos, interrupts pressure.
- Swap (hold) — partner becomes your point character. Heals gray health on the resting champion.
- Handshake Tag (during combo) — mid-combo character switch that keeps the juggle going. Your Fuse determines how many you get.
TAG ON DEFENSE
Defensive tagging is the highest-skill part of the system: a well-timed swap escapes the corner, but a predictable one hands your opponent a free combo on the incoming character.
- Never tag at the same point in blockstrings twice in a row
- Incoming characters can be anti-aired — vary your entry timing
- Save one assist for anti-pressure: it’s your combo breaker
MANAGING THE ASSIST GAUGE
Every assist call spends from a gauge that refills over time — tagging isn’t free, and running it empty strands you on a solo character with no backup at the worst possible moment:
- Treat your last assist like your last defensive resource — don’t burn it on greedy combo filler.
- The gauge recovers faster while a champion rests, so swaps aren’t only defense — they’re how you buy your assist back.
- Watch the opponent’s gauge too: an empty assist meter means their pressure is about to go quiet, and that’s your cue to push.
Elite tag play is resource management as much as timing — the player who always has an assist available is the one dictating the pace.
BUILDING TAG SYNERGY
Good duos are built around assist coverage: a zoner assist covers a brawler’s approach; a launcher assist extends a grappler’s damage. When picking duos, ask: what does my assist do for my point character’s weakest moment?
