Falconet

ROGUE MACHINES HAVE INVADED An army of intelligent machines have gone rogue in post-war cities. Your highly skilled 3-man team has been commissioned to pilot the Falconet , an advanced weapons entity, to rescue the humans trapped behind enemy lines.  On your team you have Bangs the engineer, Spike the navigator, and Flo the pilot of the Falconet . You will need to shoot your way through each retro style level to eliminate enemies… before they eliminate you.   USE WEAPONS IN COMBOS Rapidly switch between your diverse arsenal of weapons with unlimited ammo to annihilate enemies in satisfying combos.  PROGRESS BY SOLVING PUZZLES Gain access to restricted areas in each level using the Falconet’s 6 different colour-coded weapons and your problem-solving skills to take out enemies and generators.  RESCUE HUMAN SURVIVORS Search out survivors in captured areas and bring back hope to the humans you liberate.  RACK UP HIGH SCORES Beat the records you set as you improve in your gun-wielding skills.
