Oh, I mean I need to reserach sonic pistol so that I can research sonic oscillator. The typo must confused a lot of ppl. Without it, I can only attack Allen subt that size Medium or under... if it's bigger Allen sub I had to let it go.
I sold all my sonic pistol before I reserach it and now I can't research sonic oscillator. Is there any place to find sonic pistol later in the game? Coz even those very small allen sub use only sonic blaster but not pistol.
