Guns:

Pistol: The cheapest gun, should help ya get started on your journey to rip and tear through those pesky monsters!

Auto-Rifle: Weaker than the pistol although its ammo might as well be dirt-cheap! (Each ammo box for it has ~600 bullets rather than the pistol's ~120)

Shotgun: A stronger, less far-reaching but wider-shot gun that speeds YOU up while holding it, (tf2 scout reference????) though be careful as its ammo runs out quickly!

Sniper Rifle: The addon's poster boy! (or in this case poster gun), the sniper has a lotta damage though its scope zooms your screen in as well as slowing you down by ~50%, great for long range battles, not so much for CQC. (unless you git gud with it!)

Revolver: Slightly less powerful than the sniper but far more effective for CQC, the revolver is great for living out your wild-west fantasies! (just be sure to not get TB!)

hmmm i think theres another gun but i cant quite remember... ehh its probably not important

Phew, now THAT's over with, we can get into the tiers!

Material Tiers:

Copper: The worst (though cheapest by a loooooong shot) tier, having no special buffs nor good damage.

Iron: The baseline tier, has some respectable damage but no buffs, overall solid.

Gold: Did someone say... speed? although it has worse damage than copper, gold has a slight buff to its firing speed, (more noticeble on slower guns like shotgun, sniper and revolver) not enough for me to use it over iron but hey! It's an option :D

Diamond: Big damage and great PvP potential???? The diamond tier has damage superior to iron AND the ability to disable shields like axes do!

Netherite: Ohh netherite, how I love being OP! Bigger damage than even diamond! The ability to disable shields! And the speed buff from gold too??? Netherite is the most powerful (but expensive) tier of guns!

legend holds that by combining all 5 guns in their netherite tiers with a special ammo box you'll get a wonderful weapon...

Gunplay:

As listed above, different guns and tiers have different strengths and weaknesses, but how 'bout we talk about guns in general?

When using a gun you might realize that its durability runs out quick! That's because it ain't durability no more, it's ammo! How do you reload it though? Simple, have a box of the gun's ammo in your inventory and utilize the gun until its ammo runs low (be careful, letting it go fully empty will cause you to discard it!) then open your crafting menu, now you can either use the crafting book or the crafting grid, just combine the gun and the ammo and there ya go! Fully reloaded and ready to fire!

If you've played with other gun addons for bedrock you might be confused on how to shoot as those usually use ACTUAL projectiles for bullets and thus, often use the right click/left trigger to fire, that is not the case here, like in any FPS your fire button is the left click/right trigger as the guns here are technically modified spears with beeg reach (thus the Tip Of The Spear naming).
