My Downloads
Here are some blend files which I published on Blendswap.com.
Alternative you can download my files directly from Google Drive.
Have fun with it and feel free to use those files for your projects.

Here is a flying drone for the Blender Game Engine. You only need your mouse to control this drone. Also, I made a Python Script which controls the sound, the force and the rotor movement of the drone with only one property.

Here are two controllable rocket types for the Blender Game Engine. You can shoot those rockets with the left and right mouse button. Rocket 1 (Left mouse button): A Rocket which tracks the mouse cursor, as we know it from some Games. Rocket 2 (Right mouse button): A Rocket with a built-in camera is controlled by mouse movement. This Blend file only works correctly with Blender 2.72 and with higher versions, i hope.

Here is a rigged tool with many functions.
knife, skalpel, saw, beer opener / can opener, corkscrew, USB flash drive and so on….

Here is an array house example with start and end cap. You can add more floors by increase the count in the array modifiers.

Rigged handmodel for blender 2.66
With the Displacement modifier you can adjust the
thickness of the hand, each finger can be controlled
with only one bone per finger and that is a separate
bone to clench a fist.
Without subsurf modifier one hand has 512 faces,
ideal for modern first person shooter, I think.
All textures 2048px.
The hand would also used for a short movie called “Droop” by Manuel L

Here is a collection of some old game stuff i made, a result of my study the BGE (Blender 2.46). I packed everything in one blendfile.
In game you can change the Charater with the number keys 1-9, if you hold space and pressing a number , you get a other version of an Charater, there are twenty playable characters in this blend.
The environment can be partially destroyed.
IMPORTANT: The blend works correctly only with Blender 2.49
feel free to use this low poly game stuff for your projects
