Hammerfest

Hammerfest base was GDI's ultimate fortress.

Description
Hammerfest was designed, first and foremost, to be invincible, as unassailable on land as the Philadelphia was unassailable in space. This was to be accomplished through the use of a Firestorm Wall defense platform, which would enclose the base in an invincible force field. Even if these firestorm defenses failed, there were still numerous Vulcan Towers and several RPG Towers to be dealt with.

History
After its construction, Hammerfest base was assigned research: work on the powerful Disrupter technology. However, Nod forces still managed to breach GDI's European perimeter, attacking and destroying a large number of GDI, and, through the services a traitor, Michael's brother Jake McNeil, managing to capture the base. Fortunately, GDI forces managed to recapture the base by taking to the waterways. After that point, Hammerfest base was no longer considered invulnerable by any means.

At the present time, it is assumed that GDI still has control of Hammerfest base. Current plans for the facility are unknown.
