is very important in bringing your mission to life. All of the aliens and human characters are here, and you can set them guard paths etc.
Units/scripts/hacks works in the same way as the Objects list presented earlier. The first category is a big general category, and the drop-down box below that is the minor category that allows you to select a more specific group of units/scripts/hacks. Finally there's the unit list that presents you with a wide selection of units for different needs.
To get you started, click on "C, Alien, Scavenger" (note: not the "triggered" version). Then click on anywhere in the terrain, and a small spider-like Scavenger will be placed there. After you place it, you can click the Scavenger in the terrain and a highlight box will appear. You can use the Delete unit command to delete the Scavenger (or press "del"). You can also set the unit's hostility level from the drop-down menu below the unit list. The options are Hostile (unit is hostile towards player), Neutral (unit is indifferent towards the player) and Ally (unit is friendly towards the player).
Scripts is a tough nut to crack. There are a lot of options, and at first they might seem too much to handle. However, with a few simple guidelines, you'll cope with it.
To bring the Scavenger to life, select Alien, Scavenger, Guard, 000 deg from the drop-down box right below the unit list. This is basically a pre-set configuration for the Scavenger, and you'll notice that the boxes below get some values too.
If you just want normal, quite alert enemies, this is enough. If you desire different kind of behavior then you'll need to experiment on your own or wait until the documentation is updated...
One example of different behavior: Place a C, Alien, Wrencher, and then select Alien, Wrencher, Climb jump from the drop-down box. Then just save the mission and play it - you will notice that the alien will climb and then jump down. This is perfect if you want an alien jumping at the player from some dark place. There are other similar scripts too, so you might want to experiment with them. You can alter some of the scripts' settings with the Properties button.
* PageUp and PageDn raise or lower the height of a unit
* Arrow keys move units
* Mouse click selects a unit (and deselects)
* Mouse wheel up rotates a unit
* Mouse wheel down "snaps" the unit to the nearest 45 degrees
* R resets the unit (all rotations, heights etc)
