Bellow are a few vehicle suggestions based on the gameplay of infinite, Ranging from new to FPS to old all of which have a unique space in the vehicle sandbox.
M121 JACKRABBIT
source: https://www.halopedia.org/M121_Jackrabbit
Info: a duel mode vehicle which has both a drive and siege mode. In drive mode it is a fast moving forward firing scout vehicle, in seige mode it has a 360 degree firing area but looses most of its mobility.
The vehicle swaps modes by parting its wheels from bicycle to tripod mode. and raising its gun from forward locked to turret mounted.
Weapon loadout
M121A: 1x HMG similar to the warthog
M121G: 1x Rapid fire grenade launcher (see halo reach falcon)
gameplay: a rapid attack map control tool the Jackrabbit excels at getting to and locking down locations, this comes at a cost, the driver while protected from the front and rear has no side protection, and while in siege mode they are almost completely immobile unable to dodge explosives.
there is also a delay between modes preventing one from just swapping back to bike mode any time an attack starts.
VAMPIRE
source: https://www.halopedia.org/Bkowe%27nei-pattern_Vampire
Info: a heavy Anti air platform salvaged by the banished and spruced up, and by spruced up I mean its stasis beam and outer plasma cannons where removed and replaced with scrap cannon hard points. its main gun being up armored and its design slightly reworked.
The banished vampire isn’t the weak Air to Air Gunship that the covenant abandoned instead it is a heavy ground support element armed with an anti vehicle needler and heavy saturation fire.
Gameplay: a 5 player vehicle, one driver/main gunner, and 4 gun bay users. this is meant to be a hard target a tank of the sky as such it has two bonuses other air vehicles don’t first the driver has a jammer instead of a boost and second it has a built in shield blocking most light damage.
Weapons
driver: heavy needler (3 shots to combine on vehicle 2 shots to kill a player slow firing. light tracking.)
gunner x4: scrap cannon
utility
hot drop: gunners can exit the vehicle with the scrap cannon in hand doing so removes the scrap cannon from that gunner slot (with any following user using their primary weapon)
Jammer: instead of a boost the driver has a jammer, which breaks locks and prevents locks while active it has a long cool down though and only lasts 5 seconds.
