I had to shoot the propane tank and powder keg mid-air after throwing them otherwise it wouldn't unlock.Also, you can quit the encounter select right after getting the kill with the weapon, you don't have to do it till the end.Posted by Pa7ongo7 on 09 Jul 17 at 18:02 I have tried many times now and my trophy still does not unlock for me. Any tips/suggestions would be appreciated.Posted by AGNOSTICMADBALL on 08 Aug 17 at 23:28 Yeah, it was the damn powder keg for me aswell. Thought it were the big red ones in chapter 20 encounter LUL. Just get the small ones as shown in the video, throw them in the air and shoot them, super easily done with slow-motion on, if needed.Posted by PLATINBLAZE on 02 Aug 18 at 21:26 Pa7ongo7 was right, didnt count for me unless i used propane tank and shot it in midair.Posted by BroknPlaya on 01 Oct 20 at 18:11
