Team Fortress 2 Engineer buildings and Medic ÜberCharge guide
Understand stock Sentries, Dispensers, Teleporters and the standard Medi Gun charge without confusing unlockable variants.
Edition covered
The PC game introduced in 2007, focusing on its nine classes, stock equipment and established objective modes. Valve screenshots include later map updates. Unlockable weapons, seasonal modes and server modifications can change specific rules.
Build a network with a purpose

The Engineer's buildings cover different needs. A Sentry protects a limited area; a Dispenser supports nearby players; a Teleporter brings teammates forward. Putting all of them where nobody travels wastes their value.
| Building | Function | Placement priority |
|---|---|---|
| Sentry Gun | Automatically attacks enemies in range | Cover an important approach without total exposure |
| Dispenser | Supplies nearby health and ammunition | A position teammates can safely reach |
| Teleporter Entrance | Receives reinforcements | A useful route from spawn |
| Teleporter Exit | Delivers players forward | Protection from immediate enemy fire |
Build charge while staying alive
The stock Medi Gun builds charge through healing and can overheal teammates. Its ÜberCharge provides temporary invulnerability to the Medic and healing target. Choose a partner and activate before incoming damage kills you.
| Situation | Useful response | Purpose |
|---|---|---|
| Teammate is hurt behind cover | Heal them before the next entry | Restore fighting strength |
| Several players need help | Switch targets when practical | Keep more of the team active |
| Charge is ready | Coordinate with a nearby damage class | Use the protected window together |
| Enemy push threatens the Medic | Activate before dying if needed | Preserve the chance to survive |
| Partner runs beyond safe range | Reposition instead of chasing blindly | Keep the team's healer alive |
Protect the equipment during the push
A Spy's Sapper disables an Engineer building while damaging it. Watch for the sabotage cue and remove it with the appropriate tool. A Pyro checking around the position can make repairs safer.
Match the plan to equipped items
Kritzkrieg, Quick-Fix and Vaccinator charges behave differently from the stock Medi Gun. Gunslinger and other Engineer loadouts also alter standard assumptions. Inspect the item before copying a stock Sentry or ÜberCharge plan.
