Progression and Milestones

Siege to Seize becomes available earlier than some of the game's most advanced research branches, but it still demands a significant badge investment. Approach it as a calculated aggressive strategy, not a casual diversion.

Key Checkpoints and Costs

• Early Aggressive Setup: The initial six nodes cost 19,615 badges, establishing a foundational aggressive frame.
• Demolition Crew II Completion: Reaching Lv. 10 of Demolition Crew II, including all prior nodes, totals 58,745 badges.
• Late Pre-Final Block: After the defensive enhancement trio, before the final expensive nodes, the cost reaches 106,715 badges.
• Full Branch Completion: To fully finish Siege to Seize, 270,155 badges are needed. This is frequently justified by the desire to unlock Field Research.

What Comes After Siege to Seize?

For many commanders, the primary motivation for fully researching Siege to Seize isn't solely its immediate benefits, but rather the path it opens to Field Research. If this is your strategic goal, planning for the 270,155 badge commitment is essential.

Before making a full commitment, consider evaluating the comparative value against the Peace Shield research branch, especially if you're balancing aggressive and defensive badge allocation.

Quick Tips

• Prioritize Peace Shield: For most players, securing essential Peace Shield benefits before fully investing in Siege to Seize yields greater early-game survivability.
• Strategic Investment: View Siege to Seize as a deliberate, mid-to-late game combat investment, not a casual research path.
• Unlock Field Research: One of the strongest incentives to complete this branch is gaining access to the advanced Field Research tree.
• Monitor In-Game Costs: Always verify current badge costs and prerequisites directly within your game's research screen, as these can occasionally be adjusted.
