Final answer:
In many video games, the damage from right-clicking with a knife depends on whether it's a backstab or a frontal attack, such as dealing around 55 damage from the front and up to 180 as a backstab in games like CS: GO.
Step-by-step explanation:
Damage done by right-clicking a knife varies across different video games. If we're discussing popular shooter games like Counter-Strike: Global Offensive (CS: GO), right-clicking with a knife typically deals a backstab attack which inflicts a higher amount of damage compared to a left-click, which is a slashing attack. In CS: GO, right-clicking doing a backstab can do around 55 damage if it's from the front and up to 180 if it's a backstab. It's important in games to know your weapons' damage as this influences strategy and gameplay effectiveness.
