To avoid ordinances being completely random, you should not be able to get the best power weapons in your first ordinance drop. But some power weapons should only be exclusive to 2nd drop, or 3rd drop.
That way, someone can’t get a Beam rifle drop within 2 minutes of the game, they will need to earn a 2nd drop. This will also make end-game more exciting, when everyone will get stronger weapons as the game progresses.
Tier 1: Needler, Sword, Gravity Hammer, Concussion Rifle, Shotgun, Scattershot, Railgun, Damage Boost, Speed Boost, Grenade pickups, Ammo drop
Tier 2 only: Spartan Laser, Sniper rifle, Beam rifle, SAW, Sticky Launcher, Invisibility, Overshield
Tier 3 only: Binary Rifle, Rocket Launcher, Incineration Cannon
