    This mission has u starting out in the middle of the map with enemies coming from the north east and west. Each section (N, E and W) are all separated by terrain so u can single them out one by one if you want to destroy them. Firstly, you may want to play the level once just to see where everything comes from so u know what to be prepared for.

    Start by building farms with every starting villagers, advance to the next age and start building more villagers to get a steady stream of income. Personally i used one of the epic reinforcement cards u get from the marketplace guy to bring in 30 mercenaries in order to hold off the enemy at the beginning. I separated them out horses next to the northern tower, phalanx to the right tower and archers to the left. I eventually shifted the archers north to assist that position and allowed my built mounted units to take over the left.

    You will want to get a market up asap to get the gold flow goin also. There is a clearing south, just above a gold mine that will be an ideal placement of your market. Once you feel comfortable u can task a few villagers on stone and reinforce each position with another tower or two if you wish, just be careful not to spend alot of time doing so.

    The left flank was the weakest only sending infantry. the right flank was the strongest sending a mix of infantry and horses with an occasional elephant(elephants are not guaranteed (thankfully) even if you are playing against Egyptian, you will know what faction you are playing against by what units they produce). The center front sent mostly archers mixed with a few infantry. Everyone has a different playstyle and u may want to build walls and stuff thats up to you (i didnt, just built my TC's on the edge in order to reinforce the borders with a few more towers) If u can focus on building walls and massing units at the same time then go right ahead.

    Once i had all 4 TC's built i just queved up a ton of villys to get it over with. had 7 min left upon completion. I have DRASTICALLY watered down what i did to keep from writing a book. WARNING: this mission can be difficult if you are playing early on and may take a few tries to "get the hang" of it, so if u fail miserably the first time DO NOT BE SURPRISED. If you have any further questions simply post below or pm i will gladly reply asap. Im not saying my way is the only way of getting it at all and if you feel u found a better way by all means comment below and ill add it to the solution to help more people and give you credit.

    A buddy of mine quickly built a wall around his base and constructed a fortress at each pinch point to eventually claim this achievement. He had around 3 min left and DID NOT use a epic reinforcement card.

    Vandel BusterUnits change each time you play it. Think of the Neighborly Reinforcements quest. I never fought War Elephants, but I did fight plenty of Hippikons on all three of my tries and Chariot Archers on the last 2.

    Sir Stratsavvyunits change with factions! the setups are still the same through each time i played it but sometimes u play against greek sometime u play against egyptians. What the AI decides to build EXACTLY i obviously cannot predict but i can give u what to basically expect. the are barracks on left, right and center. stables to the right and archery range on center.

    I Damacon IBUT..... when i build 4TC and maximum houses, I had population limit ONLY 180, not 200. So how can i made population limit 200? 4 TCs and maximum houses is not enough...

    Sir Stratsavvyif u max out houses and TC's then u will have a 200 pop cap. i would make sure u have completed all the buildings first as they wont count if they are still under construction

    jc coldingquick question. does converted units count, and what about units that fills more than 1???
    Posted by jc colding on 01 Nov 11 at 12:51
    Sir Stratsavvyi havent converted units but i would assume they do....cant tell you for sure tho. and it doesnt matter what units u use as long as u hit the pop cap.
    Posted by Sir Stratsavvy on 01 Nov 11 at 22:33
    Vandel BusterConverted units do count. Also, things that take up 3 population count as 3 on the total. Golden Hippikons are pretty good for this quest. They train quickly and are 3 in population.
