To unlock campaign gates and expand your armory in Fieldrunners 2 for iPad for iPad, complete stages on Hard difficulty to earn all three stars at once. If an initial Hard run is too difficult, clear the stage on Casual (one star) or Medium (two stars) to advance the map and scout runner paths before returning with stronger weapons.

Difficulty Settings and Star Values

Campaign progression requires hitting specific star thresholds to remove roadblocks and access bonus levels. While clearing easier settings helps unlock immediate gates, finishing a level on Hard automatically awards all three stars without requiring previous clears on lower difficulties.

Strategies by Mission Type

Each game mode changes win conditions and requires adjustments to maze layout and tower selection.

Survival Mode: Maze Routing and Crowd Control

Survival mode requires stopping dozens of consecutive waves composed of foot soldiers, fast motorbikes, armored tanks, and aerial blimps.

  1. Establish serpentine paths early: Place cost-effective Gatling Towers at the entrance to build long switchbacks, forcing ground runners to traverse the maximum firing distance.
  2. Cluster splash damage at corners: Position Glue Towers at turns to slow runner packs, allowing Missile Towers and artillery to maximize their area-of-effect damage.
  3. Cover open airspace: Ensure anti-air coverage overlaps open flight corridors where flying blimps bypass your ground maze entirely.
  4. Invest in upgrades over expansion: Upgrade your core slow and splash zones rather than littering the map with un-upgraded base towers.

Time Trial Mode: Burst Damage at the Spawn

Time Trial levels require eliminating a set quota of runners before the timer expires. Extended mazes that slowly funnel enemies across the whole map can cause a failure, as runners spend too much time traveling instead of dying to register toward the quota.

  • Shorten the track: Funnel enemies into a tight, high-damage corridor immediately adjacent to the spawn gate.
  • Prioritize immediate burst: Deploy explosive and electrical towers that wipe out clusters on entry rather than relying on damage-over-time effects.
  • Invest gold into early choke points: Spend earned coins on upgrading damage for towers touching the entrance lanes instead of building long perimeter walls.

Sudden Death Mode: Zero-Leak Defense

Sudden Death stages grant zero life cushion; a single leaked runner results in an instant defeat.

  • Front-load slowing effects: Place crowd control at the very start of the track so fast motorbikes cannot bypass your heavy batteries.
  • Run at normal speed: Keep the speed toggle at standard velocity during mixed or heavily armored waves to monitor unit health pools.
  • Use the Rewind feature: If a runner slips past your kill zone, trigger the Rewind tool immediately to reposition towers or redirect fire before the unit exits.

Overcoming Campaign Roadblocks

When a Hard mission blocks progression, clear it on Casual or Medium to keep moving across the world map. Use the coins earned from completed runs to purchase consumable single-use items, such as landmines and airstrikes. Deploying these consumables during later Hard attempts provides an emergency safeguard against tank rushes and split-lane leaks, allowing you to secure the remaining stars once your armory expands.
