Overkill is a song by RIOT, and is their sixth single on the label. It was released on November 5, 2018.
- The cover art holds figures and symbols from every non-collaboration RIOT release in 2018 on Monstercat so far.
- Here are some of the "easter-eggs" from their previous singles' artwork:
- The skull on the dog-like monster and 2 people standing raising their hands in the front is a reference to their debut Monstercat single, Disorder.
- The two-headed dog monster is a reference to their off-label collaboration with Kayzo, Wake Up.
- The people armed with weapons are a reference to The Mob.
- The two people riding camels are a reference to Aiwa.
- The outro features "Local Forecast" a royalty-free composition from producer Kevin MacLeod.
- This song was voted 1st place in Monstercat's Best of 2018 Voting, finishing ahead of the label's biggest hit of the year, "Crab Rave" by Noisestorm.
- Noted in Overture 1990, the massive robot seen in this artwork is called the "Machine."
