Game mechanics

Level traversal

• Ability to transform from fighter plane into giant robot and back
• Plane can fly in the air and attack air targets
• This mode will move at a constant velocity without input
• Dies if it hits the ground
• Robot can walk on the ground and attack ground targets
• Robot can jump and crouch
• Can’t move in the crouch position
• When landing on a tank when the player is jumping the tank will explode
• Both modes will be able to speed up their movement speed
• In doing so this will also affect the amount of time it will take to switch direction

Health system

• Both player, allies and enemies will run off a health and shield system
• Shields can be depleted and will recharge after a set amount of time if the target is still alive
• Health can be depleted once shields are fully depleted and will not recharge
• Target will die if health is completely depleted
• If player dies then the level is restarted
• If ally or enemy dies they are removed from play

Attacks

• Two types of attacks, physical and virus
• Physical attacks destroys targets
• Physical attacks come in two types, missiles and gun
• Missiles fire as a barrage
• Can’t be fired in robot mode
• Gun fires as a continuous line
• Can be fired in both modes
• Virus attacks hack enemy targets and converts them into allies
• Virus attacks bar the use of physical for set number of time
• Virus attacks needs the target shields down to work
• Can be done in both modes

Enemies

•  Enemies will be made up of three classes
• Fighter class will be an air unit that can attack air units
• Will use gun attack
• Can be hacked
• Tank class will be a ground that can attack ground units
• Will use a slow but strong gun attack
• Can be hacked
•  Turret class will be a stationary ground unit that can attack both air and ground units
• Will use gun attack
• Can be hacked
• Movable units will spawn from both sides of the level

Win conditions

• Player wins level by uploading a virus to three points in the level
• Once a point is hacked a pulse will be sent out disabling the shields of nearby enemy units
• Once level is one player may move on to the next level

Contending with the Environment

• This game will also give you extra challenge by making contend with the environment
• One of the first environmental hazard that the player will have to contend with is the terrain, In plane mode if you come into contact with it you will die automatically, In robot mode the terrain will add to the platforming elements
• Another environmental hazard will be clouds in the air, these clouds will obscure the player view, there will be different clouds which will have varying effect on the player view
• One of the final environmental hazards that the player will have to contend with is tunnels that the player can fly though, these tunnels will essentially test player skill with flying, these tunnels are optional
