The turn is divided up into 3 parts Attack Phase, Move Phase, and Action Phase. Each unit in the Player's army can only act once per turn. This means they will either have to attack, move, or use an action. Each player alternate turns until the game is finished.
During the Attack Phase
The Player who's turn it is has the chance to attack any opponents that are in range and view of his/her units. The Player will declare what units are attacking and who they intend to target. We will roll for each unit, but let's say Player 1 has 2 units and Player 2 has 1 unit. If player 1's units are in sight of Player 2's, and he wants to attack with both, he must declare that he want's to attack with both of them and not one and then the other. A lot of players will try to chain attacks if one fails the first time, but it ruins the tempo of the game.
We'll only discuss ranged attacks at the moment. Back to the prior example Player 1 is using both of his units to fire upon player 2. So Player 1 would declare attacks and Player 2 would state his action, in this case almost always an evasion roll. Player 2 will roll a D20 and add his RFX score to the number.
Player 1 would then roll a D20 for his attack with each unit. The D20 value would be added to that unit's WPN value since this is a ranged attack. If the attacker's total value is higher than the defender's, the attack hits. If the total is the same number or in the defender's favor, the attack misses.
During the Movement Phase
The Player who's turn it is gets to next move his units that did not attack. Units have a movement value based off of their SPD attribute. Most units in the game will move anywhere from 2D6 to 4D6. This number is then measured in Inches, (I literally just now thought about the metric system and wonder if some people on here have metric only measurements.) The Player's units would move throughout the environment taking any path they please until all of the movement is used up. Certain features incur penalties or use up a given number of D6's. Once all units are moved that want to the player will go on the the next phase.
The Action Phase
This phase is where the Player decides to use any abilities or do things they could not do in the prior two phases. This includes but is not limited to; med-kits, using abilities, interacting with the environment, etc. This phase is pretty limited right now as the game is still being designed but will grow as the game does and most likely be much larger in the end.
