I'm actually really surprised with how great this game is. Really loving the amazing work put out by the team so far, and looking forward to the content on the roadmap.
Pretty much all of my gameplay suggestions have already been covered and acknowledged in other threads, so instead I'll suggest a gamemode.
I really think the game could do with a sort of "endless" mode at some point down the line. The way I'm thinking it could work is having the city procedurally generated out to a certain distance with "safe" areas between zones to act as barriers so you can unload the previous zone, randomized missions for each zone(sometimes none at all, just fighting to the next safe area), and obviously change mission parameters a bit between the zones. Would love to hear the team's thoughts on this.
