The Soldier on preparing the mercenaries to parachute out of a plane

The B.A.S.E. Jumper is a secondary weapon for the Soldier and a primary weapon for the Demoman. It is a parachuting backpack with a spade decal, a sewn-on patch with a parachute logo, a red release handle, and a tag attached to a piece of rope, with the tag reading "#64". The parachute itself is greyish white, with various holes and rips on top.

This weapon allows the wearer to, whilst in midair, press the jump key (default key: Spacebar) to activate a parachute, slowing and capping their vertical descent to 112 Hammer units (roughly 37.3% of normal speed or 4.8 mph). Air control while the parachute is deployed is reduced by 50%. Pressing the jump key again will deactivate the parachute, allowing players to fall normally. The player can not reactivate the parachute again after they deactivate it mid-air. Players can attack with any of their weapons while the parachute is deployed.

The B.A.S.E. Jumper can be deployed whenever the player is in the air, whether by jumping, explosive jumping, knockback, or simply falling off a ledge. Soldiers using the B.A.S.E. Jumper can successfully use the Market Gardener to land critical hits on players as long as the original jump was an explosive jump.

The B.A.S.E. Jumper was contributed to the Steam Workshop.


Note: This demonstration has been out of date since October 20, 2017 Patch.

  • This item cannot be worn with the backpack cosmetic items, as they occupy the same equip region.


  • One can craft the B.A.S.E. Jumper with incorrect slot and class tokens. i.e. Demoman class token with Secondary slot token. This is due to the B.A.S.E. Jumper being shared by both the Soldier and the Demoman while using different weapon slots for each class.
  • If a player dies with a deployed parachute, the parachute will stay open while the player's ragdoll falls at standard speed.
  • The B.A.S.E. Jumper doesn't show while inspecting it from the Loadout menu.
  • The B.A.S.E. Jumper doesn't appear when inspecting it from the backpack menu.


  • B.A.S.E. stands for Building, Antenna, Span (i.e., bridges), and Earth (i.e., cliffs); and the name as a whole is in reference to BASE jumping.
  • The back of the "#64" paper contains a note reading "I love Square", marked by three drawings, an eye, a heart and a square, respectively. Square is the concept artist for the B.A.S.E. Jumper.
