Yeah I included the freeze shotgun as a last resort as I wanted the players to rely more on sneaking past their aliens and be patient about their approach rather than attack and dash. Looking back I probably should've made it so that the shotgun would be a recommended use of action in some areas. Wanted to do something simple since I was experimenting with tools like Trenchbroom to design levels and get accustomed to the process of importing 3d models. Next time I'll work with someone else so I can have more time to design more levels for the player. Thanks so much for your reply!
