The Overhealer can boost a player's health to 200% of their maximum, and unlike the Medi Gun's 150% overheal, this boost will not decay over time. The trade-off is that the Overhealer's ÜberCharge was to fill very slowly or possibly not at all.
Eventually the Overhealer was shelved due to balancing issues in the game.
- This weapon's functionality is very similar to Medi Gun Beta 1, another scrapped Medi Gun with non-decaying overheal.
- This weapon was eventually replaced by the Kritzkrieg. The model and materials for the Kritzkrieg attachment bear the filename
