Jim Raynor hoped to negotiate with the Tal'darim for some of the gas. However, the Tal'darim adamantly refused; the gas was a gift from the gods and not to be disturbed by the terrans. The Raiders, in turn, refused to give up and deployed goliaths for the operation. The protoss first attempted to interfere with the extraction process, but as the Raiders grew more successful, the Tal'darim moved to seal the shrines. Nonetheless, the Raiders managed to get away with seven canisters of terrazine.
Afterward, Matt Horner received a transmission from an unknown source, explaining that one of the terrazine's uses is to enhance ghosts into spectres and accusing Gabriel Tosh of being a threat to Raynor. Tosh admitted to being a spectre, but claimed the transmission came from the Terran Dominion in an attempt to divide them. Raynor agreed to let the matter pass, but wasn't sure if he could trust Tosh.
The only way to harvest terrazine is to bring an SCV to each shrine. Harvesting time increases with difficulty. The SCV must return to the command center with the terrazine canister. The protoss attack harvesting SCVs mainly with air units; marines, medics and goliaths are the best escorts. SCVs must be escorted to the shrine and back.
Protoss counter-attacks grow stronger over time. Harvesting terrazine simultaneously from shrines in close proximity to each other may save time while limiting the size of the escort force.
The protoss attempt to seal shrines with probes preventing terrazine harvesting. The frequency of attempts increasing with difficulty. There are more shrines than required to meet the primary objective. Allowing some shrines to be sealed may save time.
Destroy the protoss base north of the starting area quickly to ease access to the rest of the map. This is important to earn the "It's So Easy" achievement. The main protoss base is on a ramp-accessible plateau to the far north. It is heavily defended by colossi, void rays and high templar. Destroying it is optional.
Do not neglect base defenses. The protoss attack through the western ramp later in the game.
There are three protoss relics that may be collected.
The nexus of the protoss camp closest to Raynor's starting base has the Akilae Tribedecal attached to it, instead of the usual Tal'darim Standard. The nexii of the main Tal'darim base utilize the Tal'darim Standard correctly. The mission "Supernova" has a similar error.
