What about taking the existing orbital strike from 2142 and making the ordnance energy bombs from bombers like the ones in the star wars moves and have a model of boomer flying over head at high altitude so that look like specks. I think that the bomber idea is very economical should be easier for the Devs  and not too difficult and time consuming meaning it comes to play quicker. But just Id want the bombs extremely power full not like the ones in 2142 they were hope less and useless. Make the bombs effective against vehicles like 2142 but have huge splash damage + huge amounts of damage like BF2 and a short response time when you order the strike. i like the idea of a laser strike from orbit from a cruser but it could take longer to program then what i propous.
