The campaign will be like this: Your a pilot stationed on a lone carrier. The carrier is attempting to link back up with fleet after being separated from the main fleet after a long battle. During the battle, the carrier had taken sever damage to it's engines & its communications are offline. When the main fleet did a head count of its ships it forgot about the severally damaged carrier, being it couldn't report in. Due to this fact, the carrier was left their by accident while the rest of the fleet
hyperspaced somewhere else. fortunately, The Carrier had a couple docked Resource Collectors, and was able to use them to repair the ship. After that with the ship being fully repaired, it began construction of new ship production facilitys to produce fighters, corvettes, & frigates to defend itself. As you complete missions in the campaign, new modules will be constructed, for example: Advanced Research module & Fire Control tower. Now i know you know halo is a first person shooter so some people are wondering like: wtf? so heres how it goes: everything you read above happens in the background. the part you play is basicaly the inside of the ship. YOu will be in a first person body, but you will be inside the ship, meaning you will be able to go inside the hanger & cabin & the bridge & the engine room & blah blah blah. while in non combat stages of the campiagn, you will be required to fulfill objectives that include: helping to repair engine problems, fighter maintence, frigate maintence, corvette maintence, and help in construction of modules. once you complete your objectives you will have the option of heading to your bunker & sleeping (if you initiate the sleep mode it just skips forward until the next combat stage, so if you wanna go a long time without combat, i suggest you don't sleep)
When in combat stages, you will need to head down to your hanger & get in either a: Fighter, Corvette, or Frigate. Choose wisely as your ship of choice will determine the outcome of your battle. Choose the wrong ship and your could buy the farm. that's all that i have for now but tell me what you think.

IF any or all of the above is not possible please tell me and i will revise the campaign to stay within the limits of the game engine.

thats really cool! But i think there should be a few level where your ship gets boarded
