OpenZone

About

OpenZone is a simple open-source cross-platform FPS/RTS game engine that is still under development. It targets to be capable of running games similar to Battlezone but with much improved functionality on both FPS and RPG levels. It runs on Linux, Windows and Native Client (inside Google Chrome/Chromium browser). OpenZone engine is a one-man project, developed entirely by Davorin Učakar.

Compared to Battlezone it has much improved FPS-level functionality. Not only you can walk into buildings, you can also open doors, use keys, elevators, switches, pick up items and put then into your inventory, push and carry around boxes, just as you would expect form any FPS game.

OpenZone uses simple AABB-based physics like Id Quake 1/2/3 or Unreal 1 engines, yet much more powerful. You can e.g. push more than one object at once, objects can be rotated, carried or thrown around. It also provides better damage model; fragile objects like a bottle can be crushed merely by running into it, others must be shot with a heavy weapon or dropped from a great height to receive any damage at all.

OpenZone is currently still under development having only limited functionality in several areas. Networking is still missing, AI is very simple and RTS support is almost non-existent. Game content currently used is more for the purpose of engine capabilities demonstration than a real game content that could be used in any finished game. Currently it features a test world, tutorial and one playable mission.
