Fieldrunners 2 for iPad for iPad: Lavaflow Ring of Fire 50-Round Guide

To clear all 50 rounds of Lavaflow: Ring of Fire in Fieldrunners 2 for iPad for iPad without taking damage, build a tight choke point along the inner loop of the track using an early Gatling and Glue setup, then transition into centralized splash damage before armored waves arrive.

Setting Up the Early Choke Point (Rounds 1–15)

Early rounds feature swarms of basic infantry and fast runners. Over-investing in heavy artillery early causes fast runners to slip through while weapons cycle their fire rates. Establish an efficient opening defense with these steps:

Anchor the inner bend: Place your first Gatling tower directly on the primary curve where incoming creeps turn inward. This position provides maximum firing uptime across both entry and exit lanes.
Add a Glue tower before round 5: Place a Glue tower immediately adjacent to your lead Gatling tower. Slowing lead runners bunches the wave together, keeping enemies under fire longer.
Funnel enemy pathing: Add secondary Gatling towers along the perimeter to close off alternate routes, forcing all ground units into your central firing arc.
Upgrade your primary tower: Promote your core Gatling tower to level 2 instead of placing scattered level 1 towers. Concentrated single-target damage handles tight clusters more reliably than unupgraded emplacements.

Countering Mid-Game Armored Waves (Rounds 16–35)

Beginning at round 16, enemy compositions shift toward armored vehicles, motorbikes, and dense columns. Standard kinetic bullets suffer reduced effectiveness against armor, requiring explosive splash damage and targeted crowd control.

Wave Phase	Primary Threat	Defense Priority	Tactical Goal
Rounds 16–22	Fast motorbikes and light armor	Leveled Glue tower with Shotgun or Missile support	Halt sprint bursts before enemies reach open lanes
Rounds 23–29	Clustered armored foot soldiers	Centralized Rocket or Mortar artillery	Apply wide-area explosive damage across grouped units
Rounds 30–35	Mixed heavy ground columns	Level 3 focused firing batteries	Shred heavy armor pools at the loop apex before paths split

Because rockets and heavy shells have projectile travel time, targets moving at full speed can outrun splash damage. Ensure your slowing field directly covers the impact zone of your heavy artillery to guarantee clean hits against bunched groups.

Fortifying Late-Game Defenses (Rounds 36–50)

The final 15 rounds deploy super-heavy units, boss-tier vehicles, and mixed composite waves. At this stage, placing low-tier distraction towers wastes cash. Maximize the upgrade tiers of your existing central battery so heavy targets take continuous damage through the innermost turn.

Maintain a single high-damage, long-range tower near the home stretch as a fallback battery. If a damaged heavy unit pushes through the primary ring, this final emplacement finishes off stragglers before they hit the exit base.

Execution Rules for a Zero-Leak Run

Avoid selling at a loss: Build only what is required for the active and upcoming wave types. Selling towers during combat wastes scrap needed for high-tier upgrades.
Cover the central airspace: Ground mazes do not redirect air units. Ensure anti-air coverage overlaps the direct flight routes over the terrain hazards.
Keep slow fields continuous: Overlapping slow debuffs keep incoming waves permanently compressed, ensuring all splash artillery hits the maximum number of targets.
