Battlescape / HUD

  • Terrain affects how much grenades and other bouncing particles bounce. See terrain definitions.
  • New tactical mission radar [1]
  • New RF and TU-reservation system
    • The TUs used for Reaction Fire are now "reserved" on the current turn (and are not used from the next turn).
      TUs will be reserved for exactly one shot in RF, but if "Multi RF" is enabled the game will shoot as many times as there are TUs left.
    • There is now a button/checkbox to reserve TUs for Crouching/Standing-Up.
    • There is also a new button that will bring up a popup to reserve TUs for shooting.
    • All reservation settings will be carried over to the next round/mission (if possible).
    • The default Reaction Fire setting (on first mission and in multiplayer) is now set correctly for all team members (and yet untested the aliens - the aliens may still need some attention).
  • If one hovers over a crouch or reload button we now have tooltips that show the needed TUs for that action and the TU-bar in the HUD will show the remaining TUs after clicking (if it's possible).
  • A new tooltip will pop up when moving the mouse over the TU-bar to show all information about TUs (includes e.g. reserved Tus). Enabled by multi-line tooltip support.
  • Stun-attacks now do not result in blood-splatters and stunned bodies only have blood around them if they are heavily wounded.
  • It is now possible to shoot over single crouched actor.
  • Key-binding improvements
  • Lots of pathfinding fixes and other fixes. Lots.
  • Bumpmapping for meshes/models on the geoscape
  • Post-processing effects (glow map support)
  • Basic implementation of mouse-based pan/tilt for battlescape


  • New LUA-based AI framework implemented, but not currently in use


  • The tooltip of items in the inventory now have a background drawn as well.
  • When manually dragging items to a soldier (i.e. his/her belt/backpack/etc...) the items are now auto-rotated to fit the available space.
    This also is used by the game when auto-placing (via the right mouse button)
  • Also if one drags an item there is now a "preview" drawn. This means you will see (while still dragging) the item in the location it'll end up when you release the mouse-button.
  • Support for scrollable containers in the soldier equipment screen. Scroll with the mouse wheel MW Template-MW.png, by clicking on the new previous/next buttons or by pressing O/P. Internally two types of scrollable container are supported:
    • Vertical (default): one item per row (weapons have their ammo drawn next to them). All main items have their name&amount listed and ammo only its amount.
    • Horizontal: The multiple items are listed in as many rows as have space in the container area.
  • New category for heavy personal equipment was added (e.g. rocket launcher, flame thrower etc.. are now listed in an extra view)


  • New display of radar coverage on geoscape
  • New XVI overlay to show XVI progression
  • Popups on the geoscape now prevents a gamer from speed up the time (you have to close them first).
