- Untitled Defense Grassland is the foundational stage where you learn the full defend-upgrade-survive loop.
- Early waves favor balanced coverage over maxing a single tower position.
- Fast Zombie and Turbot waves punish gaps in coverage, so overlap attack zones.
- Boss prep matters most: enter Chained Boss waves with upgraded damage, not raw unit count.
- Resource discipline — keep a Gold reserve so you can react when pressure spikes.
Untitled Defense Grassland Overview
The Untitled Defense Grassland is where most players spend their first hours, and it is also where the core habits of the entire game get built. The stage follows the classic tower defense loop documented across the game's official update logs: deploy defensive units along a fixed route, survive escalating waves of zombies and bots, earn Gold and crate rewards, and unlock stronger options between matches.
What makes the Grassland distinct is the enemy variety curve. Early waves send Basic Zombies that simply test your damage output, but the difficulty ramps through Fast Zombies, Ghosts, Golden Zombies, and Tank Zombies, before finishing with boss encounters such as the Chained Boss and bot-type threats like the Turbot and DynaBot. Your build order needs to respect that curve rather than treating every wave the same way.
The table below summarizes the stage's progression rhythm:
| Phase | Waves | Main Threats | Defensive Priority | | Stage opening | Early waves | Basic Zombie | Establish baseline damage and route coverage | | Ramp-up | Mid waves | Fast Zombie, Ghost | Overlap attack zones, handle special properties | | Pressure spike | Late waves | Golden Zombie, Tank Zombie | Sustained upgraded damage | | Finale | Boss waves | Chained Boss, Confinement | Maxed key positions, resource reserve |
Do not judge your Grassland defense by how easily it clears wave 1 through 3. The stage is designed so that early success tells you almost nothing about whether your setup survives the tank and boss waves. Always stress-test by planning for the late game from the start.
Grassland Enemy Reference
Every wave decision in the Grassland comes down to matching your defense against the enemy roster. Official update information documents the main enemy types, and each one creates a different kind of pressure on your layout.
| Enemy | Category | Threat Type | Recommended Response | | Basic Zombie | Zombie | Standard | Baseline target for judging consistent damage | | Fast Zombie | Zombie | Speed | Overlapping coverage, no long unprotected gaps | | Ghost | Zombie | Special | Diversify tower types, avoid single-type defense | | Golden Zombie | Zombie | Durability | Focus strongest damage sources on it early | | Tank Zombie | Zombie | High Health | Sustained upgraded damage, not low-level spam | | Basic Bot | Bot | Standard | Balanced defense while saving for later variants | | Turbot | Bot | Speed | Multiple attack zones along the path | | DynaBot | Bot | Special | Damage spread across multiple route sections | | Chained Boss | Boss | Boss | Pre-upgraded defenses at long-range chokepoints | | Confinement | Boss | Boss | Enter with upgrades done and resources remaining |
Speed Threats
- Fast Zombie / Turbot
- Escape through weak single positions
- Fix with overlapping attack zones
Durability Threats
- Tank / Golden Zombie
- Absorb huge damage totals
- Fix with upgraded sustained damage
Boss Threats
- Chained Boss / Confinement
- Dominate entire waves
- Fix with pre-wave preparation
Relying on a single strong defensive position is the most frequent Grassland failure. DynaBot and Turbot waves are balanced around punishing exactly that layout, so spread meaningful damage across multiple sections of the route.
Step-by-Step Grassland Run
Follow this build order for a stable Grassland clear. It assumes a standard solo or co-op match on the stage.
Build Reliable Early Coverage
Start with enough defensive power to stop the opening Basic Zombie waves, but do not spend every resource immediately. Place towers where they can attack enemies for as much of the route as possible, prioritizing spots with long line-of-sight over short blind corners.
Create Overlapping Attack Zones
Position defenses so at least two towers cover the same route section. This is your insurance policy against Fast Zombies and Turbots, which can pass a single weak position before it fires again.
Upgrade Before Expanding
Once basic coverage is secure, pour resources into upgrading your best existing towers instead of filling every slot with low-level units. Upgraded damage scales far better against Tank Zombies than raw unit count.
Hold a Resource Reserve
Keep Gold in reserve as waves get harder. A reserve lets you instantly upgrade when a Tank Zombie or Golden Zombie wave appears, instead of watching your under-leveled defense collapse.
Pre-Boss Reinforcement
Before the Chained Boss or Confinement arrives, max out your strongest damage positions, confirm coverage near long-range chokepoints, and avoid entering the boss wave with an underdeveloped setup.
In multiplayer Grassland runs, split responsibilities with teammates across different route sections instead of stacking every tower in the same spot. Distributed coverage handles speed and special enemies far more consistently.
Weapons and Support Options
The Grassland also involves direct combat through melee weapons documented in the official update logs. While towers carry most of the defense, weapons let you deal with enemies at close range when a section is about to break.
| Weapon | Category | Role | Best Used For | | Wooden Club | Melee | Basic close-range combat | Emergency kills on early enemies | | Metal Rod | Melee | Close-range combat | Sustained poke between tower shots | | Mace | Melee | Close-range damage | High-pressure moments near leaks | | Basic Hammer | Melee | Basic melee combat | Flexible backup option |
Weapon balance changes across updates, so compare their current damage values before committing resources to any single option. In general, treat weapons as a supplement to tower coverage, not a replacement for it.
Update logs show ongoing weapon and tower balancing. If a weapon or tower feels weaker or stronger than this guide describes, check the latest patch notes before changing your whole strategy.
Grassland Progression Checklist
Clearing the Grassland consistently feeds the game's reward loop: match completion earns Gold, and crates such as Basic Crates and Complex Crates expand the options available to your account. Use this checklist to track your run quality.
Grassland Run Milestones:
- Establish full-route coverage before wave 5
- Create at least two overlapping attack zones
- Fully upgrade one primary damage tower
- Survive a Tank Zombie wave with no leaks
- Defeat Chained Boss with a Gold reserve remaining
| Reward | Type | Progression Value | | Gold | Core resource | Flexibility for unlocks and upgrades | | Basic Crate | Crate | Entry-level rewards, early collection growth | | Complex Crate | Crate | Higher-value long-term progression rewards | | Match completion | Loop | Foundation of steady account progression |
Consistent successful Grassland clears are worth more than repeatedly failing at late waves. If your defense breaks at the same point every run, drop back, fix the specific weakness, and rebuild a stable clear before pushing difficulty.
FAQ
Q: What is the best opening setup for the Untitled Defense Grassland?
Build enough towers for full route coverage first, then overlap at least two attack zones. Avoid spending all resources in the first waves so you can react when Fast Zombies and stronger enemies appear.
Q: How do I stop Fast Zombies and Turbots from leaking?
These speed threats pass single weak positions quickly. Position multiple towers so they cover the same route section, ensuring enemies take continuous damage instead of recovering between zones.
Q: Should I add more towers or upgrade existing ones in the Grassland?
Once basic coverage is secure, upgrading your best towers is generally more efficient than adding many low-level units, especially against Tank Zombies and bosses that require sustained upgraded damage.
Q: How should I prepare for the Chained Boss and Confinement?
Upgrade your strongest damage positions before the boss wave begins, concentrate damage where the boss stays in range longest, and keep resources in reserve so you can react if the boss survives your main damage zone.
