Kill Streak/Combo Blueprint?

I’m currently working on a twin-stick shooter, and would like to have a kill streak pop up on the screen. For example, if you kill 5 enemies, back-to-back within a short time span, the game would give you a 5x Combo notification, or something of the sort. Does anyone know how to set that up?

Thank you in advance.

Every bullet checks if it kills and if it does it tells its owner, the player pawn, to add one. Inside the pawn you keep track of the number and display it using the hud.

To reset you track every tick and add the time as you go. If the time exceeds a certain limit you reset the counter. Every kill resets the timer variable.
