Marvel Snap High Voltage Overdrive Guide

High Voltage: Overdrive, or HVO, is the high-energy chaos cousin of vanilla High Voltage. Matches are short, Charged cards are shuffled into your deck, and the reactor adds Max Energy as the match goes. Once enough Charged cards have been played, the reactor explodes and adds its effect to the game. SnapComplete tracks every run. 5 High Voltage: Overdrive events have run since the mode launched. 680K games tracked in 7 days last run across 22K synced collections.

High Voltage: Overdrive is also known as HVO.

How High Voltage: Overdrive Works

HVO compresses Marvel Snap into 4 turns of rapid escalation. At game start, 8 Charged cards are shuffled into your deck, each with minus-1 cost and plus-1 power. The reactor replaces the Cube: before each of the first 3 turns it awards both players the same 2 to 4 Max Energy, stacking across turns. By turn 4 you'll have at least 18 total energy to spend, often more.

The signature mechanic is the reactor. Each Charged card played adds a charge, and after 5 charges across both sides the reactor explodes, adding a big board-wide effect pulled from a rotating pool: destroy low-power characters, give all Charged cards plus-5 Power, or transform them into brand new cards. The specific effect varies per turn and per event run, so no two games play the same.

HVO has no Cubes and no snapping, so there's no ranked stake. Wins and mission completions pay Volts, the mode's currency, which spend in the Overdrive Shop on variants, avatars, borders, and other cosmetics. Event Pass tracks and rewards vary by run.
