Missions

Missions are issued within each island you defend with your squads. Each mission has specific objectives, such as protecting/damaging certain units/buildings.

Global modifiers
All missions are affected by the difficulty level selected in the hangar: There's no penalty for unlocking islands on Easy mode first.
 * Normal: Designed to provide an interesting challenge to new and experienced players.
 * Easy Mode: Reduced enemy spawn rates. Score is reduced by 50%.
 * Hard Mode: Increased spawn rates and more Alpha Vek. Score is increased by 50%.

Local modifiers
Missions also have local difficulty modifiers:
 * Easy: Defensive shields are placed on random buildings. These missions only have one objective, that gives out one power or reputation.
 * Medium: No modifier applied. These missions either have two objectives, with each giving out one power, reputation, or Reactor Core, or one objective that gives out two power or reputation.
 * Hard: High-threat detected, meaning at least one alpha Vek and increased spawns. These missions can have up to three objectives, with the total rewards adding up to 3 of either Reactor Cores, power, or reputation.

Rewards
A mission can have from 1 to 3 objectives. Some objectives are common to all islands and some objectives are specific to certain islands.

Every mission has certain rewards granted to the player as long as they fulfil certain objectives. Most missions grant either one or two reputation points within a corporation in exchange for fulfilling a specific goal. Additionally, some missions will grant grid power in exchange for the protection of a specific building. It is also possible to get a Reactor Core during a mission.

A Time Pod may also randomly appear in a mission, requiring the player to either have a mech stand on the tile on which it appears in order to collect it or to prevent the Vek from destroying it until the end of the mission. Time pods always give the player a Reactor Core, plus a randomly selected item or pilot (Note: you will not always get an item or pilot)

For each island, if you complete all missions successfully (including rescuing any Time Pods) you get a bonus reward of the choice of either 1 item, 1 pilot or add 2 to your Power Grid (increasing Grid Defense if Power Grid is maxed out).

Strategy

 * 1 Reputation can be turned in for 1 Power Grid, so gaining Reputation is equal or better than gaining Power Grid.
 * However, Reputation can only be cashed in after completing an entire island, so direct Power Grid improvements can provide short term benefits which help in the long term.
 * Missions that offer Reactor Core rewards are difficult but often worth going after. (3 Reputation can be traded in for 1 Reactor Core.)
