Fieldrunners 2 for iPad for iPad: Be Mine Heroic Puzzle Guide

To clear the Be Mine puzzle on Heroic difficulty in Fieldrunners 2 for iPad for iPad, use your limited build credits to redirect runner pathing directly into the pre-set landmines. Basic towers cannot deal enough damage to defeat Heroic enemy waves. Victory requires treating every tower strictly as a blocking wall that forces tightly packed enemy groups across explosive tiles.

Be Mine Heroic Puzzle Mechanics

The Be Mine stage replaces standard attrition defense with an environmental puzzle. Because tower funds are severely limited and enemy health pools are high, standard weapons cannot eliminate runners before they reach the exit. The pre-placed landmines supply the required lethal area-of-effect damage.

Landmines trigger when an enemy steps onto their activation plate, but they do not respawn after exploding. If a lead runner trips a mine prematurely, trailing units will survive and bypass your remaining defenses. Your maze must force entire waves to cluster together before stepping onto each mine.

Maze Routing and Wave Clustering

Enemy pathfinding always takes the shortest unobstructed route from the spawn gate to the exit. Without interference, runners will bypass the mine pockets entirely.

To manipulate the enemy route effectively:

• Seal direct bypass routes: Place towers across the open central avenues to invalidate the default sprint path.
• Form angled deflection walls: Position barriers so runners cannot clip around mine borders without making direct contact with the trigger tile.
• Narrow the approach into choke points: Restrict the entrance to each mine zone to a single tile. This forces trailing units into a straight line directly behind the vanguard.
• Elongate the overall walk distance: Extending the path gives standard-speed units enough time to catch up with faster lead runners, ensuring the entire wave is within the blast radius when the mine detonates.

Never spend credits upgrading towers. Every coin must be reserved for placing new barriers. In addition, always verify that the updated path indicator displays a continuous line to the goal before starting the round. Completely sealing the track will invalidate placement or cause runners to break through.

Step-by-Step Heroic Execution

Follow these steps to complete the puzzle without leaking runners:

1. Inspect the grid before unpausing: Locate the fixed landmine positions and check the default path line connecting the spawn point to your base.
2. Block the central lane: Place baseline towers across the primary highway to push the calculated path outward toward the explosive hazards.
3. Build the guide walls: Construct barriers that channel the redirected path into single-file corridors leading directly over the center of the mines.
4. Confirm the route line: Check the visible pathing indicator to ensure the dotted line passes directly through each mine before releasing the wave.
5. Conserve remaining funds: Hold unspent credits until the initial runner groups detonate the forward traps, then place any remaining redirecting towers needed for later waves.
