Tag Team

Tag Team is a gameplay mechanic introduced in the 2017 game Sonic Forces. It allows the player to take control of two characters at the same time, namely Sonic the Hedgehog and the customizable Avatar, allowing the use of both characters' abilities.

Tag Team is reminiscent of similar concepts used in previous entries in the series such as Sonic Advance 3 and Sonic the Hedgehog 4: Episode II. The player, however, can not manually switch between the two heroes, and is instead done automatically when players reach a certain section of the stage they are in. Unlike individual stages, Tag Team stages are randomly spread out through the world's map and do not contain as many 2.5D sections.

The Double Boost, a collaboration technique between Sonic and the Avatar, can be activated when the player manages to fill the Boost Gauge enough.

Variations
During the third phase of the game's final boss, a variation of the Tag Team, the Triple Team, takes its place, with the player taking control of all the protagonists: Sonic, the Avatar, and Classic Sonic.
