*Let's see how much I can get done in under 15 minutes
This would go with the Odharnait Warriors thing I was thinking of.
After a brief slideshow showing the story of how the Heroes found out about Odharnait, and how it is under siege by the forces of Chaos, they fly off into space to kick some robotic ass.
This mission would be broken into 5 stages, including one Bonus Stage.
Stage 1: Defense
The Odharnait capitol of Arcem is under attack by legions of Chaos. In this stage, you must fight back waves of robots, while protecting two Shield Generators.
Thankfully the robots focus fire on you when you're in range, so you won't have to chase them down. After destroying 5 Waves of increasing difficulty, a Boss Appears, in the form of an oversized Machine Catapult Mk II, similar to Gultred from Gigan Busters. Blow that up and it's Stage Clear.
Stage 2: Counter Attack
You take to the fields between Arcem and the Chaos base, to destroy the Chaos Surface-to-Orbit Cannons and Radar Towers, allowing the Odharnait army to punch through and hit em where it hurts. Once the 4 Cannons and 3 Radar Towers are destroyed, a squad of 3 Elite Robots appear that you must destroy. Conquer them and another Stage down.
Stage 3: Assault
You assault the Chaos base under cover fire from an Odharnait warship in low orbit. The base itself is protected by a powerful defensive barrier, which must be shut down form the inside. Once you blast open the door, you must take out 4 Shield Generators, and 3 Engineer robots in order to bring down the shield. Not an easy task, considering the hefty amount of base defenses. Once the barrier is down, the Odhar ship will help clean up the large force with its gun.
Bonus: Stage 4: Cash Grab
This stage is unlike other Bonus stages, in that you are awarded UC for each target you destroy. Destroying multiple targets will increase the score multiplier, and the amount of UC you get per kill. The goal is to get the highest amount of UC possible before time runs out. Higher difficulties would increase the number of kills required in order to increase the multiplier. Don;t worry, the maximum possible amount would be around 1000 - 2000UC
Stage 5: Destruction
This stage takes place inside the Chaos base itself, similar to the final mission of Gigan Busters, only it is less like a cave and more of a military base. The base itself is rather tall, with multiple floors and Elevators to take you up to each floor. There are 7 floors in total, each with different enemies. Similar to the First Stage, only you have to go to them. ON the top floor you come face to face with the commander, a Dark painted Centaur X. He sees you, and jumps into a giant robot which becomes the Boss "Wild Cannon", as the roof of the Building opens into a launch platform. The Cannon's primary means of attacking you is the release of dozens of spherical defense drones, sort of like Autogun Bits that fly around and shoot you. It also has a scatter missile attack that it likes to shoot at AIRs. It's feet can also stomp you if you aren't careful. Its main weakness is its legs. Do enough damage to one and the robot will fall over, exposing it's Core, and allowing you to attack. After a short time, it will get back up and begin attacking and moving again. Rinse and Repeat. Once the Wild Cannon is destroyed, you fight Centaur himself, which would be a pretty straight-forward battle, if not for his super sized HP bar and Jet Lance. You win when he's exploded. Afterwards you have the eternal gratitude of the people of Odharnait, and earn a shiny new medal.
So what do you guys think? Would this be cool?
I'm still working on the potential Rewards for completing it on various difficulties.
And some clarification on enemies might be needed.
