Bacta canisters are portable, disposable packs of bacta ointments and emergency care tools. Designed for use in the field, bacta canisters can be used to heal wounds and restore vitality during medical recovery. No field medic should be without them.
The main difference between Bacta Canisters and MedPacks is that the backa is equipped to be used in the future rather than to heal instantly.
Bactas come in 2 types: Big ("Big Bacta") and normal one ("BioTech Bacta Canister").
The first type is less common and heals 50 hp. The normal bacta heals 25 hp and is a part of equipment of many Siege classes.
Bactas are also commonly used by the map creators in the role of energy drinks served in the bars.
