this is a sketch of my game level that is going to be made in 3dsmax and unity.

here is this map remade in photo shop

now as those purple rectangles are airbattle ships. ill only add them if i have time and the resources.
the objectives are numbered.
1. is secure the plain with the three rocks
2. destroy the enemy front line command post
3. destroy all turrents cannons
4. destroy the enemy reserve base
5. destroy the other enemy reserve base.
6. kill the enemy commander.
these objectives will basicly kill all enemies in that area. unless i have time and knowledge to like make more unique objectives and more objectives.

this is a render picture of the city i made in 3ds max.
this is only my first idea it may change alittle or alot.

this is one of the cannons i have made to put in this game.
there will be many of these cannon in the level. but the cannons are for destroy tanks and those air ships. if the airships are including the cannons will be fine in the game but if not then they may just sit there as they will be over kill for tanks and destroying buildings will be hard. so i might make this cannons into one huge giant one and the main objective is to destroy it before it shoots and puts a hole in the ground where the player and allies were. but as i said this idea may change alittle.
