"Raise Your Weapon" received generally positive reviews from music critics. David Jeffries from Allmusic gave the song a positive review, saying, "When the one-two punch of “Raise Your Weapon” and “One Trick Pony” introduce the Mau5’s newfound love of dubstep, you’ve got just enough variety." Will Hermes of Rolling Stone also gave a positive review, "The masterstroke is "Raise Your Weapon," which breaks down into a sick dubstep beat. "How does it feel now, to watch it burn?" asks singer Greta Svabo Bech before the bass hits". Dave Simpson of The Guardian said "Raise Your Weapon – featuring Greta Svabo Bech's soulful vocal – shows he can turn his hand to thoughtful sounds". Alex Denney of BBC Music "Raise Your Weapons lurches suddenly from vocal-led, ambient house into the dentist-drill arsenal of sounds more commonly associated with Benga". Michelangelo Matos of The A.V. Club gave the song a mixed review, calling Bech's verses "half-baked" and the use of dubstep "by-the-numbers".
