Utopia Must Fall is a browser game (for mobile too) that evokes the days of 1970s and 80s vector scan arcade games. There are nods to Asteroids, Gravitar, Tac-Scan, Space Fury and other more modern titles like Geometry Wars, with gameplay reminiscent of Missile Command but with a research and upgrade upgrade system. The password is CEASEFIRE if it asks.
Just gets stuck at an enter password screen for me. No matter what password I enter, it gives an error.
