Dungeon Hack is an open source role-playing game that has an ambition to recreate the gameplay of the second chapter of The Elder Scrolls: Daggerfall.

Short summary:

Paid: No
Type: Volunteer work
Requirements: C++, OGRE render engine
Time frame: As long as you have time and motivation

Longer story:

Dungeon hack is under development for more than a year. Unfortunately, our main coder doesn't have enough free time anymore, so we are looking for experienced C++ programmers who are willing to learn or already know how to work with OGRE render engine, OIS input system, Newton or ODE physics, TinyXML api, Lua bindings.

The project wiki where everything is documented:
dungeonhack.uesp.net

The demo and the source in a single archive:

We would be very grateful for any help.
