Words can barely describe how excellent this game is. It is a masterclass in shooting game art and design. It is simple enough that a beginner can enjoy it, and deep enough for a master to lose their mind inside. I feel like I have only scratched the surface. Even after finishing the main game, After nearly 80 hours. I still want to keep grinding at it. To do better in segments, or to get better scores. System Erasure has created, in My opinion, the greatest STG I have ever played.
