RV: Orbital Defense

Retro Vaders: Orbital Defense

Player moves in a circular orbit of the Earth firing at invading Vaders using arrow keys to rotate clockwise or anti-clockwise.

Each of the Blaster types has a normal attack and a secondary special attack and can be upgraded through its 5 stages (as in RV2) although spectrum level always stays at yellow (1) meaning that highly armoured vaders take multiple shots to kill.

Sniper Blaster
----------------
Very high movement speed, rotates very quickly and has a small mass allowing for easier bullet dodging
Primary Attack: Fires a single, high velocity projectile with a fairly quick reload speed.
Special Attack: Piercing Shot - Fires a special projectile which pierces through all Vaders in it's path, fairly quick cooldown

Spread Blaster
----------------
Slow movement speed, rotates slowly and is bulky due to it's fairly large mass.
Primary Attack: Fires multiple projectiles in a line spread with a quite slow reload speed
Special Attack: Shock and Awe - Fires a rapid burst of 3 lines of spreads in quick succession. Fairly long cool down

Rapid Blaster
----------------
High movement speed, average sized mass for a fairly balanced blaster
Primary Attack: Fires bullets with a quick cooldown, gains additional projectiles per shot at levels 4 and 5.
Special Attack: Overcharger - Auto fires with a massively increased firing rate / reload speed for a short period, average length cooldown
