Gleam is a gameplay mechanic in Double Dragon Neon.
If a player executes a well-timed crouch or dodge-roll, their character will trigger Gleam time, flashing red and dealing double damage with all attacks for the next few seconds while also instantly regaining a considerable amount of energy to perform special moves.
As such, even if the player prefers a more offensive approach, the use of Gleam should always be kept in mind for strategic use for filling up the energy bar and thus keep performing special moves longer. Likewise, certain enemies have attacks that are easier to dodge, which the player should also make use of and purposely lure them into attacking whenever required, acting as an easy source of Gleam time.
The "Rage" mix tape increases the duration of the Gleam.
