Fieldrunners 2 for iPad for iPad: How to Beat Maps Without Upgrades

To clear maps in Fieldrunners 2 for iPad for iPad without upgrading towers, you must replace compact, high-tier kill zones with sprawling, full-board serpentine mazes. Because Tier 1 towers lack individual burst damage, route length and continuous crowd control are required to wear down enemy waves before they reach the exit.

Economic Shift and Maze Construction

Restricting your defense to unupgraded towers changes how you spend cash. In standard play, currency is concentrated into high-damage Tier 2 and Tier 3 enhancements. Without upgrades, every dollar must go into placing additional Tier 1 units across open tiles.

Because individual towers fire with baseline stats, path length dictates total damage output. Apply these building rules when establishing your maze:

1. Use Gatling Towers as walls: Gatling Towers have the lowest purchase cost, making them your primary structural block for carving paths without draining early cash.
2. Snake across the entire board: Route runners back and forth over the full width and height of the map. Every added turn multiplies how many volleys adjacent turrets land on passing targets.
3. Build shared interior firing lines: Place damage towers on interior walls between two lanes rather than along the outer edges of the map. A tower placed between paths attacks enemies going down the first corridor, pivoting to fire again when they enter the return corridor.

Core Tier 1 Tower Roles

Without upgrade scaling, towers must be selected for their baseline utility, area-of-effect (AoE) coverage, or range.

• Gatling Tower: Acts almost exclusively as cheap pathing material. Its base damage drops off against mid-game armor, but it directs enemy movement at minimal cost.
• Glue Tower: Serves as your most vital asset. Base-level damage requires double the exposure time to eliminate standard targets. Stagger unupgraded Glue Towers every three to four tiles along main corridors to maintain continuous slow status.
• Flamethrower Tower: Delivers sustained line damage through stacked infantry. Place Flamethrowers at hairpin turns or pointing straight down long corridors so the flame stream hits entire clusters at once.
• Mortar Tower: Supplies wide-area splash damage that softens swarms before they enter interior lanes. Overlap two or three Mortar firing radiuses over central intersections to compensate for their slow base firing speed.

Countering Armored Waves and Leaks

Armored vehicles and high-health elites present the highest leak risk because Tier 1 projectile damage struggles against high durability.

To eliminate heavy targets without upgraded firepower, position Glue Towers immediately ahead of Flamethrower and Mortar clusters. Slowing armored targets directly inside overlapping splash zones maximizes the number of hits they take from baseline attacks.

If a fast runner or heavy vehicle slips past your main firing corridor, use dynamic rerouting:

• Drop a Tier 1 Gatling Tower directly in the open path ahead of the escaping runner to close that exit.
• Open an alternate opening further back in your maze.
• The runner AI will immediately recalculate its route, turning around to walk back through your existing firing lanes without requiring you to sell or upgrade any towers.
