Firstly i think the game is a load of fun for a long time predator fan like myself. I think it is well balanced - if you come up against a well formed Fire Team the predator has no chance, if you face an uncoordinated group then its easy work to pick through them.
I would like to see longer games though, some are over in 5 minutes.
I would also love to see the Predator be able to string people and AI up and skin them. Perhaps more vocal mimicry too.
Also be good to see all the OG Fire Team as DLC - and finally maybe for a second release but city maps with Pred 2 OG Keys and Harrigan.
