To avoid not being able to use this exploit, either do not install new patches before using this exploit or delete the patches. Note: This glitch was performed on an unpatched version of the game. You can keep collecting the weapon upgrade from the same mission since it resets each time. Then, return to Eva's Hammer to collect it again. Once you unlock the 'Uberkommandant' mission on Eva's Hammer, select a district on the map and collect the weapon upgrade kit.
The final area of the mission also has a good view of the Statue Of Liberty ruins.
There is no other map like this in the game. Successfully complete all single Ubercommander assassination missions and collect all Death Cards (except the last one) to unlock the secret 'Riverside' mission on the war room map.
