This might sound strange, but I used a flare gun on a heavy (it was a story mission, where I picked it up as my only weapon) and he burned to death. There was no way I weakened him as I had no other weapon to use, and there was no possible way I could've shanked him.
---psn is same as name Don't call me cheap when we're both holding the same gun, bro
I actually just let a tiger loose and the tiger and heavy died at the same time. There was a pirate or two shooting at the tiger as well, so I believe if it were just the two, the tiger would have lived.
