👉 An upset weapon is a term used in competitive gaming, particularly in first-person shooters like Call of Duty, referring to a weapon that is significantly more powerful or accurate than its standard counterpart, often due to a custom modification or a bug exploit. This can result in a player gaining an unfair advantage, leading to unexpected and dramatic shifts in gameplay dynamics. Upset weapons can drastically change the balance of power, making previously dominant strategies obsolete and sometimes leading to dramatic upsets where a less powerful weapon becomes the decisive factor in a match.
