I was playing crucible last night and a Titan was charging at me and caught me unawares, with little time to react, I had one rocket left in the chamber, so I naturally decided to suicide myself and take him down too. I point the rocket launcher at the ground and as he got within the blast radius, I let the rocket fly. I killed myself and the Titan escaped unscathed. I was like "derp, derp, lol wat just happened?"
