You know how the Battle for the Grassy Plains happened in the movie, and we saw the Trade Federation's what if, but what if the Gungans made it to Theed?
Personal Hints:
-Like last mission, your Assault Mechs and Fambaa Shield Generators will be your main fighting force. Have them take the lead while the other units provide backup
-Hide Jar Jar and Tarpals in one of your Mechs. They won't last long in combat otherwise
-Every fortress you destroy will give you two Repeater Troopers. Also destroying the turret and Airbase where the Jammer was in OOM-9 4 will give you two Fighters.
-When your main force crosses the second bridge, two transports full of units will appear on the west corner of the map. You can drop them off and have them meet up with your main force, but you can ignore them if you want.
-Keep your Anti-Air Mobiles alive. There aren't many air units this mission, but they're they only things that can take them down.
-You don't need to wipe the map to win. Just focus on reaching and destroying the Monument.
