3.9.1 What types of aliens are there?

Here is a list, with descriptions and notes on location, map colour, special vehicles and strengths:

3.9.2 How strong are alien forces?

The table shows the typical firepower values of alien vessels, and typical orbital defenses, at the time you can first meet them (December 3427 for most, two months earlier for Garthogs). This table is intended to give an indication of relative combat strengths, not an absolute guide:

Notes:

3.9.3 What do the relationship numbers mean?

Numbers on the diplomacy table indicate how 'good' relations are between aliens, from 0 (hate) to 100 (harmony). Values below 20 make war likely, values above 80 are often associated with alliances. War status is shown as red on the table, alliances shown in white.

3.9.4 What do the diplomacy options mean?

You can talk to alien ambassadors at any time, except for a short period after you last talked to them (they will be shown yellow on the diplomacy screen if this is the case). If you select a screen and then decide not to pick any option on it, click the right mouse button to go back. Some or all of these options will be available:

From time to time other alien races may contact you to propose one of these options, or ask for money. When they are attempting to contact you, an exclamation mark ("!") will be displayed next to the race name on the diplomacy screen.
