By Earnaldo Team • 12 min read • Tower Defense / Anime

Anime Crossover Defense by Starter Studios has crossed 20 million visits on Roblox, and it keeps growing with each new banner drop. This guide covers the strongest units, smartest summoning tactics, map-by-map strategies, and the active codes you should redeem right now. Whether you're brand new or pushing hard mode maps, you'll find actionable advice to strengthen your lineup and clear waves faster.

What Is Anime Crossover Defense?

Anime Crossover Defense is a tower defense game on Roblox where you place anime characters as defensive towers to stop waves of enemies from reaching the end of each map. Developed by Starter Studios, the game blends gacha summoning with strategic tower placement across increasingly difficult stages.

The core loop works like this: you earn gems from clearing stages, spend those gems on gacha banners to summon new units, then upgrade and deploy those units on the battlefield. Characters come from well-known anime series, and each one has unique abilities, attack ranges, and damage types that affect how they perform against different enemy types.

With over 20 million visits and a steady stream of content updates, Anime Crossover Defense sits among the most active tower defense games on the platform. New banners typically drop every 2-3 weeks, each featuring limited-time units that shake up the meta. If you enjoy games like Tower Defense Simulator or Anime Defenders, you'll feel right at home here.

Unit Tier List (April 2026)

Your unit roster determines how far you can push in Anime Crossover Defense. Not all characters perform equally, and investing in the wrong ones early can stall your progress for days. Here's the current tier ranking based on damage output, utility, and versatility across all game modes.

S-Tier Units

A-Tier Units

B-Tier Units

B-tier units are solid performers that can carry you through early and mid-game content. These include base-form versions of S-tier characters (standard Gojo, unevolved Madara), as well as niche picks like Kakashi, Vegeta, and Zenitsu. They're worth investing in if you haven't pulled anything higher, but plan to replace them once you summon A-tier or S-tier characters.

Summoning Strategy & Gem Management

Gems are the most valuable resource in Anime Crossover Defense, and how you spend them separates players who progress quickly from those who plateau. The gacha system has two banner types: standard and limited.

Standard banners are permanent and feature a rotating pool of A-tier and B-tier units with a roughly 2% chance to pull an S-tier character per summon. A single pull costs 150 gems. A 10-pull costs 1,350 gems (saving you 150 gems) and guarantees at least one A-tier or higher unit.

Limited banners run for 10-14 days and feature newly released S-tier units at a boosted 3.5% drop rate. These banners also include a pity system: after 50 pulls without an S-tier, your 51st pull is guaranteed to be the featured unit. That means you need roughly 6,750 gems to hit pity on a 10-pull basis.

How to Spend Your Gems Wisely

• Pull on the standard banner 2-3 times when you first start to build a functional roster of at least 4 units.
• Stop pulling on the standard banner once you have a solid A-tier wave clearer and a single-target DPS unit.
• Save every gem you earn from stages, dailies, and codes for the next limited banner.
• Aim for at least 3,000 gems before a limited banner drops. If you can reach 6,750, you're guaranteed the featured S-tier unit through pity.
• Never spend gems on resource refreshes or speed-ups. The gem-to-value ratio is terrible compared to summoning.

Step-by-Step Progression Guide

Progressing efficiently in Anime Crossover Defense means prioritizing the right activities at each stage of the game. Here's the path that gets you to end-game content in the least amount of time.

• Redeem all active codes before you do anything else. The free gems and tickets from codes give you an immediate advantage over players who skip this step. As of April 2026, redeeming every active code nets you 2,450 gems and 8 summon tickets.
• Clear stages 1 through 10 using your starter units. These early stages introduce basic wave patterns and tower placement fundamentals. You'll earn about 800 gems total from first-clear bonuses.
• Summon on the standard banner with your initial gems. Do 2-3 multi-pulls to build a base roster. You need at least 1 AoE unit for waves and 1 single-target DPS for bosses.
• Pour all upgrade materials into your best unit first. A fully upgraded A-tier character at level 30 deals more damage than 4 partially upgraded units at level 10. This is the single most impactful choice you'll make in the early game.
• Push through stages 11-25 to unlock raids at stage 20. These mid-game stages ramp up enemy HP significantly, so proper tower placement becomes critical. Use AoE units at the start of the path and single-target units near the end.
• Start running raids daily once they're unlocked. Raids drop exclusive upgrade shards, rare materials, and bonus gems. Aim for at least 3 raids per day. Joining a raid lobby with other players makes clearing them much easier.
• Save gems for limited banners from this point forward. With a functional roster already built, every gem should go toward the pity counter on limited banners where the strongest units appear.

Map Tactics & Tower Placement

Tower placement is where skill outweighs roster strength. A well-placed A-tier team can outperform a poorly positioned S-tier lineup on most maps. The key is understanding enemy pathing and maximizing the time each tower spends attacking.

General Placement Rules

Place AoE units at bends in the path where enemies cluster together. Corners and U-turns are the best spots because enemies spend more time in range as they navigate the turn. Your AoE towers should cover as much of the path as possible, ideally hitting enemies on 2 or more path segments simultaneously.

Single-target DPS units belong near the end of the path, positioned to hammer bosses and tanky enemies that survive the AoE gauntlet. Place them at straight sections where enemies walk in a line, giving your tower maximum uninterrupted attack time.

Support units that buff allies or debuff enemies should sit in the center of your formation where they can affect the most towers. A support unit that boosts the attack speed of 3 nearby towers is worth more than one that only reaches 1.

Boss Wave Strategy

Boss waves appear every 5 stages and feature a single powerful enemy with massive HP. Here's how to handle them effectively.

Switch your formation before the boss wave hits. If you have the Extra Slot game pass, deploy an additional single-target DPS unit specifically for the boss. Without it, consider swapping out one of your weaker AoE towers for a dedicated boss killer.

Time your ability activations carefully. Most S-tier units have burst abilities on cooldowns between 6 and 15 seconds. Don't waste them on the small enemies that spawn alongside the boss. Wait until the boss enters your kill zone, then activate all burst abilities at once for maximum damage stacking.

Slow and stun effects matter most during boss waves. Units like Todoroki Evolved (40% slow) and Awakened Gojo (4-second stun) give your DPS towers extra time to deal damage. Always keep at least one crowd control unit in your boss wave lineup.

Hard Mode Maps

Hard mode maps use the same layouts as normal but feature enemies with 3x HP and 1.5x movement speed. The rewards are doubled: you get 2x gems and 2x upgrade materials from every clear. To succeed in hard mode, you generally need a roster of at least 4 units at upgrade level 20 or higher, with at least one S-tier boss killer.

The hardest map in the current rotation is Volcanic Rift, where the path splits into two lanes at the midpoint. You need to cover both lanes with enough firepower to handle split waves. Most players run 2 AoE units (one per lane) and 2 single-target DPS units at the merge point where both lanes converge before the exit.

Game Pass Breakdown

Anime Crossover Defense offers 4 game passes, each targeting a different aspect of gameplay. Here's how they compare in terms of value for your Robux.

The VIP pass at 499 Robux provides the most long-term value. Those VIP daily missions alone yield around 200 gems per day, which means the pass pays for itself in summoning value within a few weeks of consistent play. The 2x Gems pass pairs well with it since doubling your stage clear rewards stacks with VIP bonuses.

Extra Slot at 99 Robux is the best budget option. Having a 5th tower on the field gives you a tangible power spike on every map, especially during boss waves where you can run 3 DPS units instead of 2. For under 100 Robux, it's hard to find a better investment.

Auto-Skip is a quality-of-life purchase. It doesn't increase your power or gem income, but it saves roughly 2-3 minutes per stage replay when farming materials on already-cleared maps. If you play more than 30 minutes a day, the time savings add up quickly.

Raids & Rare Materials

Raids unlock at stage 20 and represent the best source of rare upgrade materials in the game. Each raid features a unique boss with mechanics you won't see in regular stages, and the loot table includes items that don't drop anywhere else.

There are currently 4 raid tiers: Normal, Hard, Extreme, and Nightmare. Normal raids can be soloed with a decent A-tier roster, but Hard and above strongly benefit from co-op. You can join public raid lobbies or invite friends to fill a 4-player squad.

Raid Rewards by Tier

Transcendence Orbs from Nightmare raids are the rarest material in the game. You need 5 of them to fully awaken an S-tier unit to its final form. At the current drop rate of roughly 1 orb per 3-4 Nightmare clears, expect to farm raids consistently for about 2 weeks to fully awaken one character.

Daily raid attempts reset at midnight UTC. You get 5 free raid entries per day across all tiers. VIP pass holders receive 2 additional entries, bringing their total to 7. Prioritize the highest tier you can consistently clear to maximize material gains per entry.
