Dont try to bring logic into video games. Silencers and quick scoping arent realistic either and shooters had these for decades.It''s a superweapon.
Well atleast this WMD makes more sense than blowing planets up. A star is an explosion kept contained by gravity, disrupts that gravity and the star blows itself apart. Meanwhile a blowing up a planet would take such enormous energy that it makes no sense. Blowing up a star would be far easier.
