Standard Weapons:
- Primary - Syringe Gun
Listed as a Level 1 Syringe Gun in the Loadout menu. It fires low-damage projectiles at a high rate (it fires 10 syringes a second). The projectiles have a travel time and follow an arced trajectory, so it is necessary to lead a moving target and aim upward to compensate for distance. The syringe gun is reasonably accurate when the trajectory is taken into account and has a moderate damage falloff with distance.
- Secondary - Medigun
The Medigun (or sometimes refered to as the "Übergun" or "Übercannon") is the secondary weapon for the Medic class. It is a Level 1 Medigun. It can heal injured allies as well as disguised spies, and will boost the total health of the target to 150% (also called overhealing or Buffing). As the Medic keeps his beam focused on a team-mate, his ÜberCharge bar will gradually fill. The ÜberCharge meter will fill faster (2.5%/second) when healing injured team-mates or team-mates whose health is not at 150% (at 150%, 1.25%/second). When the ÜberCharge is used, the Medic and his target glow their team's color, and become invulnerable for 8 seconds.The heal rate is based on how long ago the target was damaged; if they were damaged less than 10 seconds ago, it heals at 24 health per second, if they were hit 12.5 seconds ago, you will heal them at 48 health per second, and if 15 seconds have elapsed, they will be healed at 72 health per second. source
The Medigun beam will stay locked onto its target as long as the wielding Medic keeps the attack button held down and keeps within range of the target. This allows the Medic to turn around and effectively keep an eye out for incoming enemies from behind. In Multiplayer > Advanced, there is an option to have the beam stay locked on without having to hold down the fire button (since the January 14, 2008 Patch).
When a player has been Overhealed, a team-colored "aura" follows them, kind of like a teleporter trail. For a brief period prior to the December 15, 2008 Patch) healing friendly Spies was dangerous for the spy because the glow would be the wrong color if they were disguised. This has been fixed.
- Melee - Bonesaw
The Bonesaw is the melee weapon for the Medic class. It is especially useful for taking out Spies that may be attempting to Backstab the Medic's heal target. In some cases, the bone saw is favored over the syringe gun as a combat weapon. According to Valve's statistics, the bone saw has a marginally higher critical hit rate of all other melee weapons. Its critical hit animation is an upwards sawing motion.
Unlockable Weapons:
- Primary - Blutsauger
The Blutsauger (meaning "Bloodsucker" or "Vampire" in German) is an unlockable primary weapon for the Medic class and replaces the Syringe gun. It is unlocked after 10 of the medic achievements are completed. It is currently placed as a Level 5 Needle Gun in the Loadout menu. The gun fires low-damage projectiles at a high rate (it fires 10 syringes a second). Whenever a projectile hits an enemy, three health is added to the medic who fired the shot. As compensation, the Blutsauger is unable to fire critical shots. Like the Syringe gun, the Blutsauger's projectiles have a travel time and follow an arced trajectory, so it is necessary to lead a moving target and aim upward to compensate for distance. When this trajectory is taken into account, it is reasonably accurate. It's also useful for Spy checks, as any friendly that gives health when shot is a Spy.
- Secondary - Kritzkrieg
The Kritzkrieg is an unlockable secondary weapon of the Medic class. It is a Level 8 Medigun. It is unlocked after 16 of the medic achievements are completed, excluding Milestone 1. Just like the Medigun, it can heal injured allies as well as disguised spies, and will boost the total health of the target to 150% (also called overhealing). As the Medic keeps his beam focused on a team-mate, his ÜberCharge bar will gradually fill. The ÜberCharge meter will fill faster when healing injured team-mates or team-mates whose health is not at 150%. When the ÜberCharge is used, the gun of the person being healed emits team colored sparks, and shoots 100% critical hits for the next 8 seconds. It does not work on the Knife and the Axtinguisher. It charges 25% faster than the Medigun, as of August 19, 2008 Patch. While the Medigun's beam has small cross symbols floating into the recipient, the Kritzkrieg has small yellow lines floating into the recipient as well. Note that unlike the medigun's ÜberCharge, you cannot use the Kritzkrieg's ÜberCharge on yourself.
The heal rate is based on how long ago the target was damaged; if they were damaged less than 10 seconds ago, it heals at 24 health per second, if they were hit 12.5 seconds ago, you will heal them at 48 health per second, and if 15 seconds have elapsed, they will be healed at 72 health per second. source
The Kritzkrieg beam will stay locked onto its target as long as the wielding Medic keeps the attack button held down and keeps within range of the target. This allows the Medic to turn around and effectively keep an eye out for incoming enemies from behind. In Options > Multiplayer > Advanced, there is an option to have the beam stay locked on without having to hold down the fire button (since the January 14, 2008 Patch).
The name "Kritzkrieg" is a pun on "Blitzkrieg[1]", which is German for "lightning war", a technique used by the Nazis in World War II. Before the Kritzkrieg was released, Valve stated in interviews that they were going to add an Overhealer that could permanently overheal team-mates to 200% of their standard health, but it would have a significantly worsened ÜberCharge, or be unable to ÜberCharge at all. However, this was cancelled after playtesting.
- Melee - Ubersaw
The Übersaw is an unlockable melee weapon for the Medic class and a Level 10 Bonesaw. As of a June 23, 2008 update, it is only necessary to get 20 medic achievements, excluding Milestone 1 and 2, to unlock the Übersaw. It is especially useful for taking out Spies that may be attempting to Backstab the Medic's heal target. The Übersaw has a 20% slower attack rate than the Bonesaw, but will charge any secondary Medic weapon by 25% per each successful hit. The Übersaw has a large needle in the middle, which fills up a vial in the Übersaw with a team colored fluid as the Medic's ÜberCharge meter increases. Its critical hit animation is an upwards sawing motion.
