Fieldrunners 2 for iPad for iPad: Dry Run Heroic Strategy Guide

To clear Dry Run on Heroic difficulty in Fieldrunners 2 for iPad for iPad without selling towers or using consumable items, build a permanent serpentine maze that funnels ground units through a central slow zone while anchoring the middle of the map with dedicated anti-air defense.

Heroic Constraints: No-Sell and No-Item Rules

A perfect clear under these self-imposed restrictions prohibits using inventory consumables—such as Rewind, Mines, or standard nukes—and forbids selling any placed defenses.

On Heroic difficulty, enemy health pools scale quickly, making gold efficiency vital:

• Zero Resale: Selling returns only a fraction of spent gold. Every tower placed must deliver sustained value from the opening wave to the final boss.
• Item-Free Defense: Relying strictly on tower synergy prevents gold waste and forces efficient spatial coverage rather than emergency recovery.

Early Maze Construction and Choke Points

Dry Run provides an open layout with fixed entry zones. Ground units take direct paths to your exit unless redirected by your defenses.

Setting the Serpentine Path

1. Direct the Opening Flow: Place baseline Gatling Towers near enemy entry vectors to force runners to double back across the field instead of marching straight to the exit.
2. Preserve Pathfinding: Never close the maze completely. Keep a continuous open lane so units stay on the intended snake path.
3. Target Upgrades Over Quantity: Upgrade front-facing Gatling Towers to Level 2 early rather than spreading level 1 turrets across the field. Higher damage rates quickly eliminate grouped infantry.

Anchoring with Glue Slowdown

Place your first Glue Tower directly at the primary bend of your maze. Unchecked runners pass through single-target firing arcs rapidly, but continuous slow effects double the exposure time of enemy waves inside your core damage zone.

Mid-Game Splash Damage and Vehicle Control

Single-target Gatling fire becomes insufficient as lightly armored runners are replaced by clustered vehicles and armored squads.

Shift your spending to Rocket Towers placed safely behind your maze walls:

• Maximize Cluster Impact: Position Rocket Towers slightly back from the front line so their firing arcs land on groups bunched up inside the Glue Tower zones.
• Deepen the Slow Effect: Upgrade core Glue Towers to levels 2 and 3. Lengthening the slow duration allows Rocket volleys to hit entire packs simultaneously, controlling dense waves without manual item intervention.

Defending Against Heavy Airstrikes

Air waves on Dry Run bypass ground mazes completely, traveling directly in straight lines toward your base. Because you cannot reposition towers, anti-air must be deployed before dedicated flight waves arrive.

• Central Placement: Build Anti-Air Towers near the middle of the board. Map-edge placements offer short engagement windows, whereas central positions track aircraft across their entire flight route.
• Prioritize Upgrades: Upgraded Anti-Air units provide the burst damage needed to drop armored flyers before they reach the exit. One high-tier turret performs better against dense flight waves than multiple unupgraded batteries.
• Layered Paths: Stagger your air coverage along the central corridor so that any plane surviving the initial burst remains under continuous fire until it exits the area.

Late-Game Upgrades and Boss Execution

The final waves feature heavy mechanical units and bosses with high health pools. With your maze structure complete and air coverage secured, direct all remaining gold into tier-3 upgrades:

1. Bring central Rocket and Gatling Towers to tier 3 to boost single-target and splash burst against high-armor targets.
2. Avoid building new turrets on map edges where contact time is low.
3. Keep focus strictly on the central kill zone where targets remain under permanent Glue slowdown.
