11. Open the Battlescreen Options menu. Use this to modify the firing, scrolling, and movement speed. Note that it is only possible to save, not to load, the battlescape scenario. However, the option to load will be available within the Geoscape screen, and the title menu of the game.

13. Dust off button. For UFO Crash Recovery, UFO Assault and Terror missions transport ship will then take off, leaving all the pieces not within it's initial deployment area behind. For Alien Base Assault, the pieces in the deployment area will retreat, leaving those elsewhere within the board behind. For Base Defence mission, it will concede the battle and the base to the alien without further loses to the player. Most of the units left behind will be listed as MIA and will be unavailable for the rest of the game.
14. Item carried by the piece's right hand. Left click on that area to use.
15. Reserve TU buttons. Will stop the piece from taking any action once a certain amount of TUs has been used. Those TUs may be used for reaction shots in the Alien's phase.
