Hmmm… I suppose you could also have it this way, to add a little more variety:
Tier 1 - Loadout weapons + grenades (in one package)
Tier 2 - Close-range/automatic/melee weapons:
Shotgun, Scattershot, Needler, SAW, Energy Sword, Gravity Hammer
Tier 3 - Explosive weapons/powerups:
Sticky Detonator, Concussion Rifle, Railgun, Overshield, Speed Boost, Damage Boost
Tier 4 (unavailable in arena gametypes) - Snipers:
Sniper Rifle, Beam Rifle, Binary Rifle
Tier 5 (unavailable in arena gametypes) - Heavy weapons:
Rocket Launcher, Spartan Laser, Fuel Rod Cannon, Incineration Cannon
(Perhaps Tiers 4 & 5 could be merged, but I’m still a little uncertain about that)
Although I’d much rather have Powerups placed on arena-style maps (like they used to be in the good old days), so perhaps they should be disabled in arena gametypes, along with PO Tiers 4 & 5. I came up with an idea that uses multiple Random Ordnance drops in one location, which spawns different Powerups (and Armour Abilities) just for a little variety.
If you want to see how this works, I have created a custom Haven variant, which I’ve designed to use Classic-style gametypes, as well as a Hybrid Slayer variant I’m working on. Feel free to d/l them, and have a custom game with friends to try it out. I’ve yet to test it out with other people, so any feedback/criticism would be much appreciated.
