enemy missiles and "Anti-air" weapons (ED: AA Gun, UCS: AA Plasma Cannon, LC: AA Rocket Launcher), which do incredible amounts of damage to aircraft. 3. The ED campaign introduces an "Advancement system" which allows the player to gain rank (and a cut-scene) upon earning a certain number of points, which are received when objectives are met in missions. 4. The shield system has been changed to even out the defense capabilities of the 3 factions. The power of the shields has been halved. 5. The campaign no longer revolves around sending resources to the player's home base for the construction of an evacuation fleet. Instead, all the resources on the map are added to home base funds when the player successfully destroys all enemy units in the mission and returns to base. Unlike the first game, which required careful conservation of resources to complete a mission and the game, funds are nearly unlimited on each mission. 6. Compared to the original game, all factions have received new additions to their respective arsenals, namely, the new anti-air weapons, which cannot attack ground units but are extremely effective against aerial ones. These new weapons are: the ED's AA Gun, similar to WW2-era anti-air weapons; the UCS' AA Plasma Cannon, which now explains why aircraft should be equipped with shields; and the LC AA Rocket, the one with the longest range of all. 7. New artillery weaponry also appears for the ED and UCS. These are most suitable for destroying structures from a very long distance. Although ED had monopoly over long-range nuclear ballistic missiles, they now also have a rapid firing artillery cannon, added in the most recent patch. In addition, both the ED and the UCS now possess submarine units armed with ballistic missiles (nuclear for ED, plasma for UCS). To counter this, the SDI Defense Center building has been upgraded in the patch: it now shoots down not only nuclear missiles, but the UCS Plasma Control Center's plasma bolts as well, resulting in the LC Weather Control Center remaining as the only truly unstoppable superweapon. 8. Five new chassis types were added: the ED Stealth tank, which is invisible unless its lights are on; the UCS Cargo Salamander, a treaded unit with heavy armor but with the ability to carry the AA Plasma Cannon; the LC Super Fighter, an effective air superiority fighter armed with AA missiles; the LC Fat
