How large will the Venus and mars maps be? (If possible, in comparison to old Russia or the moon)? Also, I've heard a lot about people saying there's a third subclass (one for void damage, one for solar damage, and one for ark damage) is this true? And Also, with 32 story missions, which I presume will get longer as they go along, how long should I expect the campaign to be? Also, will each strike be as large as each other? Lastly, I got halo reach and 3 to hold me off until destiny, should this ease the withdrawal enough or will I find myself quickly completing these and feeling the full effects of destiny's bitter sweet aftertaste soon again?
