I've only been playing this game 120 hours so far but it made me think of what other kinds of modes/games would suit this type of style.

Maybe a rogue-like mode where players go down into dungeons and get as far as they can against increasing enemy numbers the further they get, being rewarded with cosmetics or other in game goodies, like unique weapons etc.

It wouldn't be such a bad idea to make a full rpg with this game's mechanics. The combat is fun and engaging and when things get intense, there isn't many games like it.

Just throwing it out there, maybe someone at Fatshark can pitch it to the higher ups ;)
