The map can be found in the Custom Maps under Challenge. The version is 1.1. Please provide feedback and bug reports, even if you think it might be a bug. Also need feedback on the kill of the enemy aircraft carrier. I need to know how many turns is reasonable to go from taking the naval shipyard, to building boats, to destroying the aircraft carrier.
The concept of this map is, you gotta send up reinforcements to save a city in distress. The city is a fortress type city, with walls and turrets. It has it's own army too, with production facilities. The rumor is that the city has been working on a new weapon, which is also why the Empire has come down on the place hard.
There are a total of 3 stages to this map. The first stage is the fight to defend New Hellic City. The play duration of defending the city is 40 turns. These turns only start once you are assigned control over the city. You do not start the game defending the city, you have to first off get reinforcements there close enough to establish a connection. Once you are there, you will have to defend all 4 directions. The enemy has a setup to attack in waves, mostly using ground units, but later on brings in bombers from up North. This is why you have a Hurricane at your disposal, but should probably build more of those later from your factory. In stage 3, the enemy abuses aircraft to his fullest advantage. But in stage 1, probably 3 hurricanes max is all you will need; you start with 1. Stage 1 ends when New Hellic City is obliterated with strategic weapons of mass destruction.
Stage 2 is the fight for a tank factory. You will want to use what forces you saved from stage 1 to take the mines to the East, if not already done so, and then move up North to take the factory. A word of advice, tread lightly. The jerk loves land mines. :U
Stage 3 starts with the seal break on the bridge, followed by an enemy siege. He doesn't like that you took his factory. That's understandable. Expect ground and air attacks, not just from the bridge, but from the other side as well. The area should be possible to defend. Just make sure you don't let your foot troops die, nor any of your M.U.L.E. transport trucks. You can't replace them at this stage of the game. Actually you can't replace any transport trucks. You can get one more though from a Western depot in the farmland district. You could sneak over something to take the base, but be careful as there is a turret outside the warehouse. The building has a tank inside, along with a truck. Use the tank to take the turret down, before moving any trucks out. He might destroy your foot soldier though, so if you are going to try this, I suggest something expendable. Taking the warehouse grants a bonus of +5 materials to all buildings. This is useful, as before you had to get all your resources from either reinforcements, or from the mines, and then drive it over to your production facilities. However, it's only +5, nothing spectacular really. Still, if you had 0 trucks, at least you could use the +5 to slowly build some at the production facility located next to the enemy naval shipyard.
After you shrug off the enemy siege to your factory, you can then move up across the bridge and head towards his naval yard. Advice, bring lots of Hurricanes. The jerk commander is located on an aircraft carrier, and he loves to send regular aircraft raids on your stuff. He also has a working factory, producing units. He will use those to defend his location. Once again he loves land mines. :U
If you do manage to get up to his naval yard, there are some tricky issues to deal with. The AI of this game loves to destroy M.U.L.E. trucks, and with bombers flying around, it will be like trying to rob the bank with a swat team on your tail. Reality is, you gotta bring resources to the naval yard, build ships, and then use them as fast as possible to destroy the enemy commander. If you take too long, he sets sail and flees. If he leaves the map, you lose the mission.
