Description

Order Of Angel is a mobile/web real-time strategy (RTS) game where players build and command armies to conquer rival castles and expand their dominion. Strategic unit composition and resource management are key to success. The game features diverse unit types, each with unique abilities, demanding careful consideration when building and deploying armies.

Tech stack

• Multi worlds (multi tenancy)

  The game supports multiple distinct worlds, allowing for isolated player bases and economies. This multi-tenancy architecture provides scalability and the potential for diverse world settings or rule sets. Players can choose which world they wish to participate in.

• Generate resource per seconds

  Players generate resources (e.g., gold, wood, food) passively over time. The rate of resource generation can likely be upgraded or enhanced through various in-game mechanics.

• Unit Training

  Players can train a variety of units, each possessing unique strengths, weaknesses, and special abilities. Careful consideration of unit composition is crucial for effective army deployment. Training likely involves resource expenditure and time investment.

• Castle Conquest and Construction
  • Conquest: Players can attack and attempt to conquer other players castles. Success in battle allows the victor to claim the conquered castle and its resources.
  • Construction: Players can also establish new castles on unoccupied territories on the world map. This allows for strategic expansion and control of key resource locations.
• Unit Enhancement

  Units can be enhanced or upgraded to improve their combat effectiveness

• Resource Stealing

  Players can attempt to raid or steal resources from other players castles. This adds an element of risk and reward, encouraging both offensive and defensive strategies.

• Spying

  Players can send spy units to scout and gather information about other players castles.
