Orbital Defense Force is a 1-4 player co-op shoot 'em up roguelike game where mercenaries take on contracts from the O.D.F. (Orbital Defense Force) agency to defend planets from invaders, for a price of course. Mercenaries are compensated in scrap that they can spend in the shop for all kinds of ship upgrades and repairs. After shopping its back to accepting more contracts because you can never have too much scrap. Can you survive the waves to take on the Elite Generals?
Face the challenges of planetary defense together. Vote on which contract will be taken next. The more difficult the contract, the more you will be compensated for your work. Taking on risky contracts is always more fun with friends!
Every mercenary has perks that will benefit the whole team. From support abilities that reflect bullets or stuns enemies to damage abilities like lobbing big grenades to deal big damage.
O.D.F. has 160+ different items providing various supportive or damaging effects. Players spend scrap to purchase randomly rolled items in the shop between levels. Each mercenary also having access to their own set of items unique to them.
With differing bullets and movement patters. Ranging from small, low health ships to large, high health ones. Some shoot EMP stun bombs while others shoot large armor piercing sniper bullets. There's even a ship that has TNT strapped to it! Enemies are also randomly spawned making each wave feel a little different than previous runs.
Each boss having their own set of attacks and themes. All except the Elite Generals being randomly selected for each level. Designed to be a challenge for every mission.
Can you defeat every Elite General?
