The secondary fire's recoil can be abused for a 'Rocket Jump'.It will not be catastrophically discharged if secondary fire is held for too long.It uses an unknown fuel source that can allow it to be used indefinitely.The vehicle-mounted Tau Cannon used during the time of the rebellion against the Combine is a more advanced model in several aspects: However, if charged for more than 10 seconds, it explodes, causing 50 damage to the user, though the weapon is left unaffected.When released, it launches a penetrating beam that does significant damage. The secondary fire allows the player to charge the weapon by forcing Uranium into it.The primary fire consumes two ammo per shot and semi-automatically fires singular beams.
If not obtained there, it can be found in the Lambda Reactor Core supply depot at the end of the chapter Lambda Core.Ī particle accelerator custom-built by BMRF scientists, it consumes depleted Uranium 235 as ammo and fires devastating beams. Tau Cannon can be first found in the Half-Life chapter Questionable Ethics, on the second floor of the Advanced Biological Research Lab.
