i beat all missions on rank X (excluding the first one of course, because thats literally impossible - the last enemy is unreachable), tried all play styles, characters and weapons, even found a few easter eggs (or easter cats really). it seems that i seen all content there is currently. i think i need to stop playing this game, at the same time i don't want to. really hope this game will be finished, because so far, it became one of the best shooters i played. thanks Author, your work is appreciated.
