Sentry jump

Sentry rocket jumping on An Engineer rocket jumping on Yukon.

A Sentry rocket jump refers to using the knock back effect of an explosion from a Level 3 Sentry gun to propel yourself great distances at the cost of some health. This tactic is frequently used by Engineers to go to unusual places in maps in order to place a Sentry nest that may be difficult to destroy. They may also place Teleporters in places that players would not normally go.

Basics

The same tactics as normal Rocket jumping apply:

• Fire the rockets from a level 3 Sentry gun at your feet using the Wrangler, crouch in mid-air for maximum height.
  • Once this tactic is mastered, a skilled engineer can pack-up the Sentry gun that just launched him right before he is launched away, allowing him to redeploy the Sentry in a new place quickly.
