My opinions, so don't take this seriously. Enjoy :D Opinions welcome.
All gun sprites from Robot Destructor. Music taken from here: https://scratch.mit.edu/projects/829501910/ Why I placed these guns where they are? Down below. ▼△▼△▼△▼△▼S TIER▼△▼△▼△▼△▼ M16: My main weapon, so I have an bias. It's well rounded overall, good mag size, dependable damage, just a well-rounded gun. Its also the first gun I got good at when I first joined, so I have a special place for it in my heart. Shotgun: (I had to rank it S or I risk getting people mad) Its great, 5 round spread can guarantee a hit even if it wasn't aimed directly at the enemy, has a neat tech where you double jump and on the second jump you shoot and ride the recoil, doubling your jump height, and overall great damage. A lot of my friends use it and I see why. ▼△▼△▼△▼△▼A TIER▼△▼△▼△▼△▼ Knife: A high risk, high reward weapon. Deals insane damage at the cost of getting up close and thus being more vulnerable. Also the only secondary weapon in the current game. Medic Gun: Its fun to use as a support, but that's about its only goal unless you want to play risky and use knife. Then its an absolute beast if you play correctly and why its ranked so high ;) ▼△▼△▼△▼△▼B TIER▼△▼△▼△▼△▼ SMG: Its ranked higher because it can actually disarm RPG rockets with its high fire rate, which is a neat tech and helps with the RPG spammer problem. Otherwise high-tier mid. It's just a M16 with lower damage, higher firerate and larger mag (only by 2 bullets). Stealth AR: Fell off hard, great against people who use fast builds and rush often, but slow fire rate makes it very niche. Hampered further by a small magazine size. It may not be good, but it once was. also it has a pretty interesting design. ▼△▼△▼△▼△▼C TIER▼△▼△▼△▼△▼ Stealth SMG: Great damage, but small magazine size and the fast firerate makes it hard to conserve bullets. It's good against cowards. Sniper: Its overall mid, great damage but heavily held back by cloud delay and lag, as well as a small magazine and long reload, making you vulnerable to being attacked during reload. ▼△▼△▼△▼△▼D TIER▼△▼△▼△▼△▼ Super Shotgun: (The only thing saving it from E is its close-range capabilities) Its...Decent? It has good damage close quarters but suffers from the fact that it has such a big spread that all the damage is gone after the bullets travel a bit. RPG: Lowest of all due to spammers and just the point-and click gameplay. The splash damage is good but its annoying because they don't really need to aim... But I may just be harsh on it because its used mostly by spammers (and especially hackers). No E tiers and level ratings, surprising! (Well ofc there's bias)
