Locations: Explore the Call of Duty Universe

Siege features a variety of planets and iconic locations from the Call of Duty lore. Players can explore these environments to gain resources, engage in battles, and expand their territory.

Key Locations Include:

  • Earth – The central hub for human factions and key supply routes.

  • Mars – A strategic planet for mining resources and staging attacks.

  • Mercury – Often the site of critical PvP battles due to its strategic value.

Each location provides unique missions and rewards, ensuring gameplay remains dynamic and challenging.

Factions: Choose Your Allegiance

Players in Siege can align with various factions from the Infinite Warfare universe. Each faction has distinct strengths, units, and tactics.

Notable Factions:

  • Settlement Defense Front (SDF) – Aggressive and expansionist, focused on conquering planets.

  • United Nations Space Alliance (UNSA) – Defensive and strategic, excelling in coordinated attacks.

  • Solar Associated Treaty Organization (SATO) – Specialized in high-tech weaponry and elite units.

  • JTF Wolverines & Saber Team – Elite squads that provide specialized cards for PvP and base defense.

Choosing a faction strategically affects your gameplay style and the type of cards and bonuses you can access.

Vehicles: Strategic Tools for Battle

Vehicles play a crucial role in both offense and defense within Siege. Players can use them to transport resources or to execute tactical maneuvers in PvP matches.

Key Vehicles Include:

  • Raven – A fast reconnaissance craft ideal for scouting enemy bases.

  • SWC-141 Retribution – Heavily armed assault vehicle perfect for breaking enemy defenses.

Vehicles can be upgraded and enhanced using Supply Drops, adding another layer of strategy for players familiar with COD BO7 mechanics.

Star Map: Navigate and Conquer

The Star Map allows players to choose which planets to scout and conquer. Each planet may contain enemy bases, resources, and strategic bonuses. Successfully attacking and defending these locations rewards players with platinum, Supply Drops, and rare cards.


Some planets contain hidden events or rare enemies that can unlock exclusive COD BO7 cards.



Scouting carefully is critical; planetary selection can determine whether you gain resources efficiently or face heavy losses.



Base Editor: Build a Fortress

In Siege, Base Editor is your tool to build and customize your home base. Players can construct defenses to prevent attacks and optimize their layouts for PvP battles.


Strategic base design is essential to survive in ranked PvP battles, especially when facing top-tier players.



Cards obtained from Supply Drops can enhance base defenses, making it harder for enemies to breach your fortifications.



Defensive structures range from turrets to energy shields.

Supply Ship and Supply Drops: The Key to Progress

Supply Ships transport crucial resources, like platinum, to your base. These resources are gathered from captured regions and are essential for upgrading characters, vehicles, and bases.

Supply Drops are central to progression:

  • Unlock new characters from Infinite Warfare.

  • Gain resources to strengthen units and defenses.

  • Vary in rarity, impacting the power of the cards obtained.

Players can earn Supply Drops by completing daily missions, defeating enemy SDF bases, or using CODPoints from the Quartermaster. This ties directly into the COD BO7 progression system, rewarding consistent gameplay and strategy.

PvP Battles: Compete and Climb the Leaderboards

Player vs Player (PvP) battles are where strategy meets skill. Winning PvP matches rewards:

  • League points and higher leaderboard rankings.

  • Supply Drops and rare cards.

Losing a match results in decreased league scores and lower rankings, so careful deck building and strategic planning are vital. Advanced players can use character synergies from COD BO7 to gain an edge over opponents.

Alliances: Strength in Numbers

Players can join or create alliances to collaborate with others, donate cards, and share resources. Alliances are crucial for:

  • Coordinated PvP attacks.

  • Defense strategies for allied bases.

  • Access to alliance-exclusive rewards.

Alliances promote a social aspect, making Siege more than just a strategy game—it’s a community-driven experience.

Call of Duty: Siege successfully brings the COD universe to mobile strategy gameplay, integrating beloved characters, factions, and mechanics familiar to fans of COD BO7. With its combination of card collection, tactical battles, base building, and PvP competition, Siege offers a deep and engaging experience for both casual and hardcore players. If you love strategy games and are a fan of the Call of Duty series, Siege is a mobile game worth exploring.
