After meeting with the "members of Avalanche" you will talk to Polk who will introduce you to the game "Fort Condor" which is a table top RTS (real time strategy) game you can challenge people around Midgar. Polk will set you up with the starter pack containing a Starter board and some base level units. When you win you will be awarded with additional units and Condor Coins you use to purchase units from "Old Snapper" (the guy dressed up like a turtle). As you beat opponents and level up, more items will be unlocked for purchase with him so check this regularly.

Fight them in the order listed because some unlockable units will help you in the next battle

The game is played by you spawning units on the board and the goal is to destroy the opponents bases (2 outposts, 1 HQ). To win you must destroy their HQ or have more bases left standing before the timer runs out. Units will automatically march forward (unless they are turrets) and attack the enemy.

Each unit has an ATB cost required to place on the board. The ATB bar refills over time and is a the top of the screen. The speed of refill is determined on what board you use.

Once you've deployed a unit type onto the board, the unit card goes to the bottom of the queue and will be unable to be played until other units have been deployed and they go to the bottom of the queue. The wait time is usually 2 but it depends on what board you're using for that match. This is to prevent zerg rushes and this rule applies to both you and the CPU.

Untis will lose HP overtime regardless if they are being attacked or not. Just to prevent either you or the CPU from just stacking units.

Units are assigned one of three roles. Vanguard (sword icon), Ranged (crossbow icon) and Defense (shield icon). These roles determine what enemies a unit is effective against:

• Vanguard (sword icon) units are effective against ranged units(crossbow icon)
  
• Ranged (crossbow icon) units are effective against defense units (shield icon)
  
• Defense (shield icon) units are effective against vanguard units (sword icon)

The units role is displayed above them and the advantages/disadvantages will be highlighted. You can view the diagram that will illustrate this relationship during the match

You can move the cursor anywhere within your own territory as far as your farthest unit has advanced. If you extend the front line deeper into the enemy territory to press the advantage. You cannot give orders to your units to attack. They will automatically asses it's surroundings and will attack on its own.

you can use certain materia during the match based on what game board you are using. There are circle icons listing what materia is used on that board. use the command prompt that it's assigned to and select the area you wish use the materia attack. they can only be used ONCE per battle so be sure you're using them wisely. magic works differently in that they don't deal elemental damage instead have a unique attack pattern. You can attack the opponents bases/HQ with materia attacks directly regardless of how far back the white line is (see Fog of War section).

The board you use determines the speed the ATB charges and the amount of unique units you can use in the game. Also it determines the types of materia attacks you can use during the match.

As your units march up, you'll see a white line progressively move forward as your lead unit is making their way to the opponents bases. You can deploy units anywhere behind this line. If your furthest most unit is destroyed, the white line will fall back to your next furtherst unit and pushing back your attack. Best to spawn units right at that line if you can in case the CPU spawns units infront of your marching unit.

This guide will help you get the achievement Game, Set, Match and NOT "Condor Queen". These load outs is what I used during my play through and what helped me win. It really depends on your ability to tactically plan out your moves. What I did was I'd have one side where I'd provoke them to send all their units to attack my main force while I sneakily sent units on the other side of the map to attack their forts. Also keep the offensive going if you're units are right at one of their bases but mind that the enemy isn't attacking yours.
