My best discription of this movie when I think about it now is action/horror? I think, might even be thriller not sure.

All I can remember is the meat of the movie where marines were sent on a misson to escort a possible government project under raps, and when something went wrong, one of the soldiers noticed fluid leakin from a canister that happened to be in this crate, and it absorbed into his hand, and he started to slowly change into a wolf like creature, (but it was way more cool looking haha)and he ended up killing his team to conceal it and one teammate lived and called the government for ground support and it slowly turnd into a cover up with him killing everything around him as he changed and finally became something else! Toward the end he ended up killing himself on a mine trip wire. That's all I can remember of this movie? I want to say it was species, subspeices? Something to do with shapeshifter of the sort?? If anyone knows I'm dyn to know the name of it!! Lol

Its not subspeices cause that's an old vampire movie from the late 80s I don't know the name of your movie though sorry
