I think predator mode should be more than just Ustanak. Otherwise call it Ustanak mode lol. I think it would be fun to have multiple predators; for that there are more than just one predator in the game. For instance, a really fun thing would have the chain saw guy (forgot his name) be one of the playable characters and crest a boss selection option. Also some of Derek Simmons's transformations? Still with the general rules applying and game survival along with killing him
