Copter Besieged

Use your acrobatic flight skills to fight off invasions of escalating monster waves each lasting 20-90 seconds. Level up your copter and buy items to fill your copters 8 slots and optimise your monster fighting.
Invasions are set in scenic 200x200m arenas and typically last 45 minutes with plenty of unlockables and configurable difficulty.

LEARN TO FLY
The flight courses are a great way to learn to fly or a chill experience between games.

Prove your competence with obstacles and targets or up your competitive edge by racing against ghosts of previous runs, friends or leaderboard players.
CUSTOMISE YOUR LOADOUT
Choose your copter based on your desired approach to the invasion.

Select your starter weapon.

Between waves use earned level ups to upgrade your copter and collected coins to buy new items.
PHYSICS BASED FLIGHT
Flight mechanics are as realistic as possible while maximising the fun. Reverse thrust provides a seamless way to get off the ground and there is no propwash or zero thrust instability. 
Upgrade your copter between waves of invasions or test and try out copter builds at the flight circuits without limit.

The game is ideally played in full acrobatic mode where the copter doesn't fly for you but there is configurable auto-leveling and auto-thrust options that are intended to be reduced as you gain experience flying.
The tutorial guides you to choosing the best setup for your current skill level where the easiest option hovers and always returns to level when there is no user input.
