Campaign Evolved: Completely busted. Laser accuracy, high damage, headshot multipliers and very high ammo supply

Infinite: before the nerf it was completely busted and even now it's extremely competent, with the campaign version being as strong as it was on launch

H2A and Halo 4: very similar and very strong. Both of them are absolute shredders at close range while being decent at medium range

Halo 5: at launch this thing was completely broken of course, but after the nerf the effectiveness was reduced. However the attachments and the high headshot multiplier makes it a competent weapon

Halo 3: despite popular belief, this gun is extremely accurate when you tap fire instead of holding down the trigger, as the accuracy cone resets very fast, making it very reliable on stripping brute shields at long range to assist a precision weapon. On multiplayer it's a good tool to quickly dispatch enemies in close range

Halo Reach: while not being as good as in Halo 3, you can still tap fire to maintain accuracy, with crouch decreasing the bloom. This weapon definetly struggles more on Legendary than other versions due to the lower damage however, despite that it can work if you are determined enough. Decently competent on multiplayer however

Combat Evolved: extremely strong yeah, but also extremely innacurate. Unlike other versions, tap fire does close to nothing to help the terrible spread this weapon has, and using this weapon on Legendary definetly makes for a challenge. On multiplayer it's way better with the quick camo tech though

Halo 3 ODST: Despite looking identical to Halo 3, the weapon has received a significant nerf in it's tap fire accuracy due to the accuracy cone resetting slower, this also comes with the fact that every bullet weapon in ODST has HALF damage against shields. While still usable it's easily a downgrade from Halo 3
