Reaching wave 100 in astd infinite mode separates casual defenders from true veterans. While the early waves feel familiar, the scaling health pools and relentless boss spawns demand a completely different approach to team building, economy management, and unit placement. This astd infinity tower guide breaks down exactly what changes after wave 50, which units carry their weight, and how to structure your economy so you never hit a damage wall.
The Infinity Tower in All Star Tower Defense is where the game's meta gets stress-tested. Unlike Story Mode, where you know the enemy composition ahead of time, infinite mode throws escalating surprises at you. Understanding the wave scaling curve and preparing your roster accordingly is the difference between a wave 60 collapse and a wave 120 run. Let's get into the specifics that matter.
Why astd Infinite Mode Demands a Different Strategy
The core reason most players fail past wave 70 isn't a lack of strong units — it's a lack of sustainable damage scaling. In Story Mode, you can brute-force most maps with a couple of maxed-out DPS units. In astd infinite mode, enemy HP grows exponentially, which means your damage output must grow at the same rate or you'll get overwhelmed.
The official Roblox page describes the Infinity Tower as a mode where you "team up with friends" and face endless waves. What that description doesn't tell you is the economy curve — the amount of cash you earn per kill stays relatively flat, while upgrade costs balloon. This creates a tension that defines the entire mode.
Here's what changes as you progress deeper:
-
Enemy HP scaling accelerates sharply after wave 50, roughly doubling every 10 waves
-
Boss waves appear more frequently, sometimes back-to-back with only 2-3 normal waves between them
-
Cash income per kill increases slowly, forcing you to maximize every upgrade purchase
-
Unit slots become the bottleneck — you can't just add more towers, you need the right mix
Because of these factors, your team composition matters more than raw unit rarity. A coordinated squad of mid-tier units with complementary abilities often outperforms a random collection of top-tier units that don't synergize. This is why studying the all star tower defense game modes overview helps — each mode rewards different playstyles, and infinite mode specifically rewards economy efficiency and ability timing.
Building Your Wave 100 Team Composition
Your roster for astd infinite mode needs to cover four essential roles: boss killer, crowd control, support buffer, and economy unit. Missing any of these creates a weakness that the mode will exploit. According to community reports from players who've cleared wave 100+, the most successful teams follow a similar structural pattern.
The Boss Killer Role
Bosses in the Infinity Tower have massive HP pools and high defense values. You need units that deal percentage-based damage or have armor-piercing attacks to handle them efficiently. Units like Gogeta and Blackbeard are frequently cited in community tier lists as top boss killers because their abilities bypass defense mechanics.
| Unit | Role | Best Wave Range | Key Ability |
|---|---|---|---|
| Gogeta | Boss DPS | 60-120 | Armor-piercing beam |
| Blackbeard | Boss DPS | 55-110 | Darkness AoE + defense shred |
| Ichigo (Bankai) | Hybrid DPS | 50-100 | High single-target burst |
| Luffy (Gear 5) | AoE + Boss | 45-95 | Extended range punches |
The key insight is that boss killers need to be placed early in your build order. Since they're expensive to max out, starting them on wave 1-5 ensures they're fully upgraded by the time the first major boss appears around wave 20. Waiting until wave 30 to place your main DPS means you'll be playing catch-up for the rest of the run.
Crowd Control and Support Units
While boss killers handle the big threats, crowd control units keep the normal waves from overwhelming your defenses. Slowing effects, stuns, and knockbacks buy your DPS units precious seconds to eliminate targets. Support units that boost attack speed or damage percentage amplify your entire team's output.
Support stacking is a strategy that veteran players swear by. If you have two units that each provide a 20% damage buff, they stack multiplicatively, giving you 44% total extra damage. This compounds significantly over the course of a long run, which is why astd infinite mode rewards buff stacking over simply adding more raw damage.
Economy Timings That Sustain Endless Waves
The single biggest mistake new players make in astd infinite mode is upgrading too aggressively early on. While it feels good to max out your first unit by wave 10, this starves your economy for the mid-game. The optimal approach follows a balanced investment curve that prioritizes income generation during the first 15 waves.
Your farm units — units that generate bonus cash per kill — should be placed and upgraded to at least level 3 before you invest heavily in DPS. This ensures you have a steady income stream that compounds throughout the run. According to player testing, a well-timed farm strategy can increase your total income by 30-40% by wave 50.
| Wave Range | Economy Focus | Upgrade Priority |
|---|---|---|
| 1-10 | Place 2-3 farm units | Farm units to level 3 |
| 11-20 | Start DPS placement | DPS to level 4-5 |
| 21-35 | Balance farms + DPS | Farms to level 5, DPS to level 6 |
| 36-50 | Max out farms | All farms to max level |
| 51+ | Pure DPS investment | DPS units to max level |
The critical transition happens around wave 35-40. If your farms aren't maxed by this point, you'll struggle to afford the expensive upgrades that wave 50+ requires. This is also when you should start considering whether your current team composition can handle the scaling, or if you need to pivot.
Timing your unit evolutions is equally important. Most units have an evolution that significantly boosts their stats, but these evolutions are expensive. Saving up for an evolution at the right moment — just before a boss wave — can be the difference between a clean kill and a leaked boss that wipes half your defenses.
Comparing astd Infinite Mode to Raids and Tournament
Understanding how astd infinite mode relates to other endgame content helps you allocate your resources wisely. The all star tower defense raids system, tournament mode, and PvP all share some mechanics with infinite mode, but each has distinct requirements that change your unit priorities.
The raids system in All Star Tower Defense focuses on coordinated team play against specific boss encounters. Raids require specialized counters — units that exploit a boss's elemental weakness or resist its abilities. In contrast, astd infinite mode demands generalist coverage because you never know exactly what's coming next.
| Mode | Primary Challenge | Best Unit Type | Team Size |
|---|---|---|---|
| astd infinite mode | Endless scaling | Balanced hybrid units | Solo or co-op |
| Raids | Boss mechanics | Specialized counters | 2-4 players |
| Tournament | Time-limited waves | High burst damage | Solo |
| PvP | Player defense | Fast deployment | 1v1 |
The tournament mode shares the most similarities with infinite mode, since both feature escalating waves and limited resources. However, tournament matches are time-limited, which means you need front-loaded damage rather than long-term scaling. Units that deal massive damage immediately, even if they fall off later, perform better in tournaments.
For players who enjoy the competitive aspect, the all star tower defense pvp scene offers a different kind of challenge. PvP matches test your ability to read opponents and adapt your strategy on the fly. While the unit tier lists overlap between PvP and infinite mode, the placement strategies differ significantly because PvP has a much smaller map.

Advanced Strategies for Wave 100 and Beyond
Once you've mastered the basics of astd infinite mode, these advanced techniques will push your runs deeper. The difference between wave 80 and wave 120 often comes down to micro-optimizations that compound over dozens of waves.
Positioning and Range Optimization
Map awareness is critical in the Infinity Tower. Most maps have choke points where enemies cluster together, making them ideal for AoE units. Placing your crowd control units at these choke points maximizes their effectiveness, while your boss killers should be positioned to cover the longest stretch of track possible.
Range buffs from support units can extend your DPS coverage significantly. If you stack two range buffs on a single unit, you can often cover two full track loops, effectively doubling its damage output. This is especially powerful on maps with long straightaways where enemies travel in predictable paths.
Ability Rotation Management
Many top-tier units have active abilities with cooldowns. Managing these cooldowns effectively — saving burst abilities for boss waves and using sustained abilities during normal waves — can dramatically increase your total damage output. According to community testing, players who actively manage ability rotations clear waves 15-20% faster than those who let abilities fire automatically.
The key is to stagger your abilities so you always have one ready. If all your burst abilities are on cooldown simultaneously, you're vulnerable during that window. By rotating which units use their abilities first, you maintain consistent pressure on the enemy wave.
When to Sell and Rebuild
Sometimes, your early-game units become obsolete by wave 60. Holding onto them wastes valuable unit slots that could be filled with stronger options. Selling a unit refunds a percentage of your investment, which you can then reinvest into better units.
The optimal sell timing is right after a boss wave, when you have a few waves of breathing room to rebuild. This minimizes the risk of being caught with an incomplete defense during a difficult wave. Veteran players typically sell their early-game farm units around wave 50-60, replacing them with pure DPS once their income needs are met.
Frequently Asked Questions
What is the best team composition for astd infinite mode?
The most reliable composition includes one boss killer like Gogeta, two crowd control units with slowing effects, one support buffer that boosts attack speed, and two farm units for economy. This balanced setup covers all four essential roles while leaving room for flexibility. Adjust the ratio based on your unit collection and the specific map layout.
How do I survive past wave 100 in the Infinity Tower?
Surviving past wave 100 requires maxed-out farm units by wave 40, a fully evolved boss killer by wave 60, and consistent ability management during boss waves. Focus on stacking damage buffs from support units, as multiplicative buffs become increasingly valuable as enemy HP scales. Also, consider selling early-game units around wave 70 to make room for stronger options.
Is astd infinite mode better for solo or co-op play?
Co-op play is generally easier because you can divide roles between players — one focuses on economy while the other handles DPS. However, solo play is more rewarding for players who want to test their personal skill. The difficulty scales with player count, so co-op doesn't reduce the challenge, but it does allow for more specialized team compositions.
How does astd infinite mode compare to raids and tournament?
Infinite mode emphasizes long-term scaling and economy management, while raids focus on boss mechanics and specific counters. Tournament mode rewards burst damage within a time limit, and PvP tests adaptability against human opponents. Each mode requires different unit priorities, so build your roster with multiple modes in mind.
What units should I prioritize for my gems?
Prioritize hybrids like Ichigo (Bankai) or Luffy (Gear 5)—they handle both boss nukes and mob clear, saving gem slots. Re-check tier lists after every patch; balance shifts can demote a meta unit overnight. For wave 100, invest in one maxed carry over several half-built supports.
