Quite cool. At first it is unclear what to do, and collisions with the droids don't seem to be happening, but i figured it out in the end. The ending is sweet. Pretty satisfying firing a superweapon at the "boss". Like Resident Evil.
On my comp, the ground is completely flat, and no sea is visible. Not surprised about the water, since it's a shader, and most shaders in DBP games don't work on my comp. Not sure why the ground would be flat though.
The framerate was low. I got 8 fps. When i complete the mission and it allows me to wander around, framerate goes up to 23!
Graphics look cool, nice sound. Controls were well documented and the help F1 thing was nice to see. Fast loading. Work out what's killing the framerate and why the ground isn't bumpy and i'll enjoy it more though.
