Are the weapon variants that are in the btb unlimited fiesta matches available in all fiesta modes or just that one?
Also, is there somewhere that lists them all with the description? There’s a couple I’m not sure what the difference is. A white hammer, I oddly feel like makes me jump higher and the striker sidekick, not sure at all what it does different, for starters.
I don’t know what everyone does but here is a list of all the abilities I know so far
Skewer Variant: Cause mini explosion and has area of effect damage.
Plasma pistol variant: When charge it fires multiple shots at the same time
BR variant: better at close range
Cindershot variant: Bullets Blow up into even smaller explosive projectiles.
Sniper: Has larger clip
Shock rifle variant: Stops vehicles in 1 hit not 2
Bulldog variant: Shoots faster
Pulse carbine variant: Shoots way faster
Sentinel beam variant; Stronger but less ammo
Energy Sword Variant: Increases movement speed
Disruptor Variant: More AEO damage
Stalker rifle variant: Close range friendly stalker rifle with faster fire rate and shorter scope
Rocket Launcher Variant: Tracks on enemies automatically
Mangler Variant: Shoots more like a shotgun with the bullets splitting into 3 different projectiles.
Hammer Variant (That white one you used): Makes you faster and pushes objects and enemies away.
Ravager Variant: Projectiles bounce 
Needler variant: Tracks enemies better and has tighter bullet spread.
Heatwave variant: Tracks enemies
That is all the current variants I know off will update list if I find more.
