With Comet Crash you not only defend your base against  rushes of enemies, but you also get to fight back with your own massive army!

There are two basic types of units that you can build: 'Basic Ops' and 'Special Ops'.

Basic Ops units are created more quickly than Special Ops units and are used to overwhelm the enemy base. There are 4 types of Basic Ops units that can be built, each with varying strengths speeds and abilities.

Special Ops are advanced units that build more slowly than Basic Ops units. Special Ops units can be used against the enemy for offensive or defensive purposes depending on the ability of the Special Ops unit.

Your army can consist of up to 1000 units!

You can build 'spawn towers' to generate Special Ops and Basic Ops units. Each tower produces a new unit every few seconds and transports it to your base where it will wait for your attack command. The more spawn towers you build, the faster your army will increase. Your base can hold up to 1000 units.

Building Basic Ops Units:

Navigate your ship to any empty area on the map. To build Basic Ops units bring up the build menu by pressing R1. Use the arrow keys to select the Basic Ops spawn tower. Press 'X' to build.

To create different types of Basic Ops units, use resources to purchase upgrades for existing spawn towers. To view the cost and upgrade attributes for the next available Basic Ops unit hover over the spawn tower. To upgrade, hover over the tower and press 'O'.  Each time a spawn tower is upgraded a new black mark will appear on each corner of the platform. When a spawn tower is fully upgraded the platform will grow and the corners will turn solid black.

To switch between available Basic Ops units hover over the spawn tower and hold down 'X'.

Building Special Ops Units:

Navigate your ship to any empty area on the map. To build Special Ops units bring up the build menu by pressing R1. Use the arrow keys to select the 'Special Ops' unit. Press 'X' to build the spawn tower for the Hammer. To choose available Special Ops units hover over the Hammer spawn tower and hold down 'X'.

The total size of your army can be viewed in the player status bar to the left of the map (just look for the sword). You can also determine how many of each type of unit you currently possess by opening the attack menu (R3). The color coded dots tell you how many units of a specific type you possess.

1 white dot = 1 Unit
1 blue dot = 10 Units
1 red dot = 100 Units

It is time to cause major turmoil with your massive army of destruction. To view the attack menu select R3. To release a particular unit type tilt the right stick toward the desired unit. The yellow bar shows you when the current attack is locked. At this point it is no longer necessary to tilt the right stick as the selected unit will automatically advance from your base. To unlock the attack, tilt the right stick in any direction.

Every enemy weapon and spawn tower in Comet Crash can be destroyed by taking it out using your arsenal. This type of assault is one of many strategies that can be used to advance in the game.

If you decide you no longer require a spawn tower you can recycle it. When you recycle a spawn tower you will also recycle some of the resources that you spent on it. Damaged spawn towers are worth less than fully repaired spawn towers. To see what a spawn tower's recycle value is, hover over the spawn tower. The greater the damage to a spawn tower, the less you will receive for recycling it.

To recycle a spawn tower press the 'SQUARE' button.

Spawn towers can be damaged by enemy fire. If a spawn tower is damaged enough it will be destroyed. To repair, hover your ship over the spawn tower to display the repair cost. The greater the damage, the more it will cost to repair.

Press 'TRIANGLE' to repair a spawn tower.

There are 4 types of weapons that can be used to defend your base against enemy swarms. You can manipulate the enemy path by strategically placing weapons along the path (you will learn more about this by completing Comet Crash training). You can also defend your base using certain types of Special Ops units.

Weapons are purchased with resources (Thorium). To see how much a weapon costs, bring up the Build Menu by pressing R1 and then select the weapon. To build a weapon, navigate your ship to an empty square on the map and press 'X'. The weapon range is shown  by a dashed red circle that surrounds the weapon when it is first built.  You can always see the range of a weapon by hovering over it.

Hover over a weapon to view its cost and upgrade attributes. Press 'O' to upgrade the weapon. Each time a weapon is upgraded a new black mark will appear on each corner of the platform. When a weapon is fully upgraded the base will grow and the corners will turn solid black.

If you decide you no longer require a weapon you can recycle it. When you recycle a weapon you will also recycle some of the resources that you spent on it. Damaged weapons are worth less than fully repaired weapons. To see what a weapon's recycle value is, hover over the weapon with your ship. The greater the damage to a weapon, the less you will receive for recycling it.

To recycle a weapon press the 'SQUARE' button.

Weapons can be damaged by enemy fire. If a weapon receives too much damage it will be destroyed. You can hover over the weapon to display the repair cost. The greater the damage, the more it will cost to repair.

Press 'TRIANGLE' to repair a weapon.

After selecting Battle mode choose the number of players that will participate in the carnage. You can choose up to 4 players. Next select the map that meets your challenge requirements. The symbols below the map represent the amount of resources (Thorium) available to you and your foes during the battle. After selecting a map it is time to select a team.  Players that desire to go head to head can select the default options. For those who prefer team play, simply change the team names so that they are the same. This means you can create even matches of 2v2 or gang up on the Comet Crash guru in the group with combinations of 3v1 and 2v1!

After selecting Battle, choose the default hit count for each player's base by changing the value for 'Max Hits'. You can choose to allow each player to take between 1 and 100 hits before he meets his defeat. Use this feature to determine the length of the battle. Will it be a lengthy assault of skill and wit, or an accelerated race of instinct and reflex?

Tired of uneven matches and comet bullies?  There is a solution...change the team strength!

After selecting Battle, choose a value for 'Max Hits' and then select a Battle map. Next change the 'Strength' setting to adjust the amount of resources and the 'Hit Count' for each player.  For example, if the 'Hit Count'  is set to 100  and the initial resources are 1000 Thorium, then choosing 50% for Team A will reduce the 'Hit Count' to 50 and the initial resources to 500 Thorium. Team B will continue to have 1000 Thorium and a 'Hit Count' of 100.

Selecting R3 in Battle Mode will pop up the Attack Menu which displays the current target in the center. To change targets hit L1.

Navigate your ship to any square on the map that is not covered by a rock or another player's base. Press 'X' to build your base.
