Atom Bomb Guide for OpenFront.io

Key Takeaway: The Atom Bomb is a tactical nuclear weapon ideal for striking concentrated enemy infrastructure. Use it to eliminate clusters of defensive or economic buildings, then follow up with conventional forces to exploit weakened borders.

1. Overview

The Atom Bomb is the smallest-yield nuclear missile in OpenFront.io’s arsenal. It delivers a powerful fission blast over a limited radius, making it most effective against tightly packed targets such as Cities, Ports, Defense Posts, and Missile Silos.

2. Build Requirements

• Prerequisite Building: Missile Silo
• Terrain: Land only (cannot be built on water)
• Availability: Requires an existing Missile Silo to launch.

3. Core Statistics

• Cost: 750,000 Gold
• Cooldown: ~10 seconds
• Yield Area: Small radius
• Build Category: [MS] Missile

4. Usage and Tactics

• Primary Targets: Groups of Cities, Ports, Defense Posts, or Enemy Missile Silos positioned closely together.
• Tactical Role:
  • Softening Defenses: Eliminate or heavily damage clustered defense posts to create exploitable breaches.
  • Economic Disruption: Wipe out Port clusters to halt enemy gold flow.
• Optimal Timing: Deploy immediately before an invasion push or to preemptively strike high-value infrastructure ahead of a follow-up land assault.

“Generally you only want to use this to pelt structure-dense areas, such as two adjacent Cities or a Port and Missile Silo.”

5. Counters and Limitations

• Anti-Nuclear Defense:
  • SAM Launcher: 75% chance to intercept an incoming Atom Bomb; cannot intercept MIRVs.
• Resource Intensive: Requires a fully built Missile Silo (1,000,000 Gold) and carries its own significant cost.
• Cooldown Management: ~10 s cooldown restricts rapid successive launches; consider spacing attacks or combining with MIRV for sustained pressure.

6. Advanced Tips

• SAM “Cooldown Bait”: Launch an Atom Bomb first, forcing enemy SAMs onto cooldown, then immediately follow with a Hydrogen Bomb to ensure passage of the larger blast.
• Concentration Strikes: Stack multiple Atom Bombs on a single Missile Silo to unleash rapid successive strikes before the enemy can rebuild defenses.
• Diversion & Feint: Use an Atom Bomb against a low-value cluster to draw SAM fire, then redirect a MIRV at a critical target in a different region.

Mastering the Atom Bomb’s precise yield and timing will grant you the edge in dismantling enemy infrastructure efficiently and opening borders for your advance.
