We only have 1 Agent (Raze) who had the HE grenade-based ability (Paint Shells), while we have already 5+ agents that have smokes, flashes, and molly-based abilities. We need another HE grenade.

For a new agent, we should have another HE Grenade-Based concept ability that is alternative to Raze (similar to Sova and Fade). It is similar to other fps games (CS:GO) where is explode after certain seconds, but the player can activate early mid-air similar to Fade abilities (optional).

Here are my Non-Visually Appealing concept ability mechanics image for the possible new agent with some small explanations and sort of red asterisks.

Another HE grenade based agent ability concept.

P.S. I'm not sure it this concept is too OP for the new agent, BUT we should have another HE grenade-based agent.
