Here are XBOX gamepad equivalence with keyboard+mouse :)

Left Stick = W S A D - movement like in FPS games
Right Stick = mouse move
A = Mouse 1 - action (shooting, picking up, using of items)
B = R - radar
X = I - inventory and P - camera (photo)
Y = Space - speed boost
Left shoulder = I - inventory
D pad up = Mouse scroll / scroll button - switching between harpoon, camera and radar
D pad down = H - spear gun (harpoon)
D pad left = M - map
D pad right = P - camera (photo)
Left/Right trigger = Z X - camera zoom in / out

This obviously does not seem very handy, but things can be changed by editing the Controls\character.ini file

Thanks for your quick reply, Faith.

Im sorry but this game got probably no manual, thats why I posted this guide (based on my in-game experiences :) also Im not experienced in HW setup, so I cant help you with X360 controller :(

Thanks for the information. Please let me know how I can get a PDF version of the Depth Hunter 2 game manual or instructions? I also cannot get my Xbox 360 Rock Candy game controller to work. Can you assist me with these two things. Thank you, Bruce B. Campbell bcampy4@gmail.com
