Project Outline

  • Zork-like adventure game
  • Type: text-based game
  • Possible platform: Web/XHTML/HTML5, Terminal
  • MMORPG-ish (killing, leveling, etc. involved) , but text-based game and it's all about statistics
    • No maps!

Project Description

Ganglands is a multiplayer, text-based adventure game in the vein of Zork and King’s Quest. Players compete to become the greatest mob boss in the ganglands by forging alliances, engaging in combat, and solving devious puzzles. Each task successfully accomplished garners experience points and money, which can be used to level up your characters and buy tools and manpower that help you claw your way to the top. Ongoing contests give you access to special bonuses and a leaderboard keeps track of your various accomplishments.
