History of Caldera

Overview

Caldera is a Solo Ops activity on Kepler (the in-game description is "Push back on encroaching enemy forces before they become entrenched."). Solo Ops are launched from the Director under Vanguard Ops, on the Solo tab. One source places the mission on Europa instead of Kepler; the in-game data used here lists Kepler, so treat the location as unconfirmed. Solo Ops come in tiers from Normal up to Ultimate, with the grade you earn scaling the reward tier, and runs take about 5-10 minutes.

Encounters and mechanics

There are two parts: sabotage three objectives in any order, then defeat a boss. The enemy faction varies.

• Vex version: destroy three dark matter cubes. The boss is a large Harpy; destroy the Vex data cubes to drop its invulnerability shield.
• Fallen version: destroy three supply depots (detonating shanks helps). The boss fight is two Captains; damage whichever is not currently invulnerable.

Area-of-effect weapons such as grenade launchers speed up the objectives. Because of its short, simple layout Caldera is widely recommended for solo power and currency grinding.

Rewards

Caldera shares the Solo Ops / Fireteam Ops loot pool of weapons and armor with set bonuses, listed on this page. Drops depend on grade and reward tier.
