Critical hits (often shortened to crits or full crits) are a damage mechanic that do extra damage on certain conditions, such as the Kritzkrieg's ÜberCharge or randomly in certain Melee weapons. When a critical hit is landed on a player, a special sound effect accompanies the hit as well as the text "CRITICAL HIT!!!" in green or "MINI-CRIT!" in yellow for critical hits and mini crits respectively is displayed above their head. Buildings are immune to both types.
Critical hits are easy to distinguish from their normal counterparts. Melee weapons get a different animation for crits, projectiles have a team-colored glow and sparkle effect, fire gains team-colored particles effects while bullets gain a team-colored trail. Alongside these visual effects there is an electrical crackling sound that accompanies these.
Critical hits increase a weapon's base damage by 3. For example, a normal pipe does 100 damage on direct hit. A critical pipe by contrast deals 300 damage on direct hit. Furthermore, critical hits ignore damage ramp-up and fall-off. A Soldier rocket deals diminished damage at range. With maximum fall-off, it only deals 48 damage. However, a critical rocket ignores this while tripling its damage, dealing a whopping 270 damage at any range.
Random critical hits
Random critical hits often shortened to random crits is a mechanic present in Team Fortress 2 live where any weapon has a random chance to hit. This mechanic has been removed from Team Fortress 2 Classic, on all except melee weapons.
A weapon's random crit chance depends on how much damage has already been done previously by the player, possibly reaching 60% random crit chance. Due to this, Snipers and Demomen have some of the highest random crit chance due to their high damage output, and Medics due to healing done contributing to the random crit chance.
Mini crits can be thought of as less extreme critical hits. Instead of tripling a weapon's damage, they only increase it by 35%. They too like critical hits ignore damage fall-off, but unlike critical hits they factor damage ramp-up. Full critical hits override mini crits. For instance, if an enemy is Marked for Death but you manage to hit a critical hit, the mini-crit will be ignore and will instead factor the normal critical hit. It is because of this critical hits are sometimes referred to as full crits to distinguish them from mini-crits.
A crit boost is a state when a weapon will deal guaranteed critical hits for a certain duration of time. A crit boost is shown by the weapon glowing the team's respective color, with sparks of electricity surging from it, accompanied by an electric sound effect. This does not affect weapons such as the Sandvich which do not deal damage. The visual effects will still be present however.
There is also a mini-crit version also present. Unlike its counterpart, a mini-crit boosted weapon does not emit electrical particle effects or emit any sound effect. The weapon does change color slightly, yellow for RED and green blue for BLU.
A crit boost can be achieved via the following events:
- Being ÜberCharged by the Kritzkrieg allows any weapon to gain critical hits for 8 seconds.
- During Humiliation at the end of a round the weapons on the winning team are crit-boosted until the round ends.
- Capturing the intelligence in Capture the Flag gives the capturing team critical hits for 10 seconds.
- The Harvester can gain a critical boost when the HEAT meter is filled. This lasts until it is used on an enemy player.
- The Chekhov's Punch can gain a critical hit boost when hitting an enemy with a melee attack with the Chekhov's. This stores up to 3 critical hits which can be used on the Heavy's other weapons. The Chekhov's themselves can only crit when at full capacity.
- The Civilian class can give a mini-crit boost to a player on the same team, granting them mini-crits for 8 seconds.
There are some cases that allow a weapon to deal guaranteed crits or mini-crits.
List of Weapons that can deal situational critical hits:
|Flare Gun||Pyro||Flares only crit on burning targets.|
|Harvester||Pyro||Deals one guaranteed critical hit after building up the HEAT meter.|
|Chekhov's Punch||Heavy||Each melee hit stores one critical hit, which can be used on Heavy's other weapons. When 3 critical hits are stored, Heavy will deal critical hits with his melee. However, the opposite is true, any melee will also deal critical damage against the Heavy.|

List of Weapons that allow for other players or weapons to deal critical hits or mini-crits:

|Fishwhacker||Sniper||The Fishwhacker when missing marks the user for death, causing all attcks to mini-crit.|
|Tranquilizer Gun||Spy||When a player is hit with the Tranquilizer Gun, all melee attacks become critical hits.|
