We'd like you to execute an attack on the Gran Mining Facility. Kisaragi has played a leading role in the mine's operation and just recently uncovered a rich vein of rare metal ore.

Needless to say, the ore has considerable value and we're unwilling to allow Kisaragi to corner the market.""After consultation with other corporations, it was decided that the mine's resources are to be equally distributed and that we, Mirage, will take over its day-to-day operations.

However, although Kisaragi agreed to this, they continue to mine the ore and are in clear violation of the arrangement that was settled upon.

We want to avoid damage to the mine and its assets, but all Kisaragi personnel are to be removed from the facility.



Laine Meyers:Raven, destroy all forces occupying the facility. Avoid damaging any of the mine equipment.

Laine Meyers:Destruction of all enemy targets confirmed. Great work, Raven.


Funds: 6000c

Note: Spartan, Cold Heart, Huntress and Scylla are still MT pilots in this mission. Also note that you cannot obtain an S-rank if you choose to bring a consort.


Sniper Rifles work well to destroy the MTs in the mine, and are less likely to destroy any crates, etc. Additionally, you are only charged a fee for destroyed equipment if you destroy it, not if an enemy does.

This is another mission with a strict time limit when aiming for an S-rank.
