In-game names where possible

Simple “what it does” explanations

Pick-better-upgrades helper

Some online guides use different EVO names. For example, many call the Forcefield EVO “Quantum Ball”, but your game shows it as “Force Barrier”. This guide tries to match the names you actually see on screen, and explains in plain language what each thing does and how it helps your run.

⚔️ Active Skills Attacks you pick during a run

🔁Boomerang

Lane Clear

Throws boomerangs that fly forward and then back, hitting enemies twice in a line. Great for clearing horizontal lanes in front of you.

Early crowd damage Pairs with Hi-Power Magnet → Magnetic Rebounder

A spiky fruit orbits around you and constantly damages nearby enemies. Great for shredding anything that gets too close.

Start with the rapid-fire drone as your main weapon. Great for constant pressure on enemies.

Aggressive playstyle

🧠 How to Use This Quick decision rules

Rule 1: Have a boss killer

Always make sure you have at least one strong single-target option: Kunai / Spirit Shuriken, Drill Shot / Whistling Arrow, RPG / Sharkmaw Gun, or Lightning / Supercell.

Rule 2: Have a crowd clearer

You also need something that deletes big waves: Molotov / Fuel Barrel, Lightning / Supercell, Guardian / Defender, or Durian / Caltrops are all great.

Rule 3: Grab cooldown early

Energy Cube is almost always a good early pick. More attacks per second = more damage = faster clearing.

Rule 4: Grab % damage early

Hi-Power Bullet boosts all damage, including your main weapon and every skill. Very safe and strong scaling.

Rule 5: Take 1–2 survivability passives

Fitness Guide, Ronin Oyoroi, and Energy Drink all help you stay alive through late-game swarms.

Rule 6: If you’re under-leveled, fix EXP

If you feel weak or stuck at low levels, grab Koga Ninja Scroll or Hi-Power Magnet so you get more EXP and level-up options.

Tip: Don’t stress about making “perfect” choices every time. Use this as a feel-good guide: grab at least one boss killer, one crowd clearer, a damage passive, a cooldown passive, and one or two survival upgrades—and you’ll already be playing way smarter than the game expects. 💫

📊 Maxed EVO Tier List Most OP → still good

S Tier – Super OP when maxed

These feel crazy strong and can often carry entire runs.

• Spirit Shuriken (Kunai + Scroll) – Auto-aim boss deleter, very safe to use.
• Eternal Light (Lightchaser + Oyoroi) – Giant light waves, insane crowd control.
• Gloom Nova (Void Power + Exo-Bracer) – Huge void bursts, amazing late-game AoE.
• Divine Destroyer (Destroyer + Medi-Drone) – Massive DPS plus healing; “pet” that carries you.
• Supercell (Lightning + Energy Cube) – Lightning storm all over the screen; great everywhere.

• Sharkmaw Gun (RPG + HE Fuel) – Explosive boss and elite killer.
• Gatling (Shotgun + Hi-Power Bullet) – Shreds anything in your face very quickly.

A Tier – Very strong, reliable picks

Great to have, just a bit less “broken” than S tier.

• Death Ray (Laser + Energy Cube) – Strong beam; positioning matters but power is high.
• Fuel Barrel (Molotov + Oil Bond) – Carpet of fire; waves melt if they walk through.
• Caltrops (Durian + HE Fuel) – Big, constant orbit damage around you.
• Defender (Guardian + Exo-Bracer) – Great protection and damage at the same time.
• Force Barrier (Forcefield + Energy Drink) – Very comfy “don’t touch me” bubble.
• Magnetic Rebounder (Boomerang + Magnet) – Lots of hits along its path, good lane control.
• Whistling Arrow (Drill + Thruster) – Strong focused damage over a line or on bosses.
• Lucille (Bat + Fitness Guide) – Excellent control weapon for close-range play.
• Reaper (Revolver + Hi-Power Bullet) – Solid single-target damage with crits.

B Tier – Fun / situational but usable

Still workable, just not as insane as the top picks.

• 1-Ton Iron (Brick + Fitness Guide) – Strong overhead bonks, but a bit random.
• Soccer Ball EVO (Soccer + Shoes) – Bouncy chaos; fun but less reliable damage.
• Inferno / Thunderbolt Bomb (Mines + Molotov/Lightning) – Nice extra burst; not core.
• Base (non-EVO) skills like unevolved Molotov/Guardian – fine early, but you want EVOs later.

How to read this tier list

• S Tier = priority if available, especially for bosses or late-game waves.
• A Tier = always good and can easily carry if you play well.
• B Tier = still okay, more for fun or specific builds you enjoy.

This is a feel-based ranking: it assumes you can actually get the EVO (right skill + right passive) and reach max level. If a combo looks fun to you, it’s always okay to pick it even if it isn’t “S tier” — fun builds are OP for your mood. 💜
