Fieldrunners 2 for iPad for iPad: Home On Derange Endless Maze Guide

To survive deep into Heroic mode on Grasslands: Home On Derange in Fieldrunners 2 for iPad for iPad, you must build an open-field serpentine maze that maximizes enemy travel distance, layers continuous crowd control, and uses gate juggling to redirect heavily damaged waves. Reaching four-digit rounds, such as round 1840, was documented specifically on release version 1.0, where early damage calculations and responsive path recalculations allowed prolonged survival. On later revisions, these same pathing fundamentals remain mandatory, though balance changes cap total endurance earlier.

Serpentine Maze Layout and Path Lengthening

Because Home On Derange is an open field, funneled single-lane defenses fail when high-tier runners sprint past single-target towers. You must route runners across the entire board horizontally multiple times before allowing them to approach the exit.

Anchor perimeter lanes first: Place low-cost towers along the outer boundaries to establish horizontal lanes from the left spawn edge across to the right side.
Keep turnarounds wide initially: Maintain two-tile gaps at outer turning points while establishing the route to avoid accidentally blocking the path and triggering runner breakthroughs.
Consolidate shared interior walls: Position your heaviest damage towers along dividers shared between parallel lanes so single towers can fire on enemies during both passes.
Set up a gate-juggling node: Place an inexpensive tower at a central lane partition. Selling and rebuilding this single tower recalculates the enemy path toward an alternate loop, forcing bosses and tanks to walk back through your primary kill zone.

Core Tower Synergies for Extended Waves

Raw bullet damage falls off sharply as enemy health scales. High-round defense relies on chaining status effects to keep runners trapped in continuous area-of-effect and piercing beam fire.

Tower Type	Optimal Placement	High-Round Function
Slowing / Glue Towers	Maze turns and lane entrances	Cuts runner speed, grouping waves together for area-of-effect strikes.
Spark / Tesla Towers	Shared interior partition walls	Fires multi-target electrical arcs to strip armor and shields from dense swarms.
Plasma / Laser Towers	Long straightaways parallel to lanes	Penetrates full files of heavily armored units with continuous linear beams.
Mortar / Nuke Towers	Central interior tiles	Delivers broad splash damage across adjacent corridors to soften clustered targets.
Gatling Towers	Outer boundary walls and gate points	Provides low-cost path obstruction and cheap sell-rebuild gate switching.

Countering Fast Runners, Armor, and Air Waves

Different enemy archetypes exploit specific weaknesses in an open-field labyrinth:

Fast Runners: Sprinters slip through if slow effects drop. Stagger your Glue or Ice towers at short, recurring intervals along the corridor rather than clumping them at the entrance. This ensures runners exiting one slow field are immediately tagged by the next before regaining full speed.
Armored Tanks and Bosses: Heavy vehicles absorb massive standard damage. Align Plasma and Laser towers directly down your longest straight corridors so continuous piercing beams strike multiple units in a straight line.
Planes and Blimps: Air units ignore ground mazes and fly directly toward the base. Place anti-air or hybrid towers within the center of the map rather than on the edges. Centralized placement allows air defenses to fire across the entire flight path without occupying critical perimeter mazing tiles.

Economy and Upgrade Priority

Surviving deep rounds requires strict gold conservation:

Prioritize length over upgrades early: Establish the full geometric maze using basic tier-1 towers before purchasing tier-2 or tier-3 upgrades. A long track lined with basic towers deals more aggregate damage than a short track with a few expensive towers.
Upgrade crowd control first: Once the path is sealed, upgrade slow towers to increase their area of effect and slow duration, ensuring ground units remain tightly packed.
Upgrade shared-wall damage next: Invest gold into central Mortar, Spark, and Laser towers that cover multiple lanes simultaneously.
Do not sell high-tier towers: Selling returns only a fraction of spent gold. Reserve sell actions exclusively for cheap gate-juggling nodes to preserve your bank for late-wave spikes.
