As discussed last week, I have shifted my focus from developing flashy effects to starting practical programming of the game. Last night I improved the map, you can now change between squad members by clicking on them with the cursor (which doubles as crosshairs when directly controlling the troops) and also added preliminary support for 'Radio messages', which will appear as text along the top of the screen to aid you with hints as proceed through the game.

Next two things to work on: AI Pathfinding (being able to command your troops to move to a particular location) and doors.
