the computer can make the following
1) if he starts with 2 bases at the beginning it will start with 6 bases without buying them :S
2) build 6 buildings at the same time :S
3) build 6 kerovs at the same time :S ;S :S
4) build 6 tanks and 6 soldiers at the same time
5) build any 6 from any thing at the same time
to check it out just play it as unhollony allience mod by openning the ra2.ini file and in skirmish sektion just change
the game mod to 4 and don't change the map
and also building 12 war factories and 12 barracks will make the buying time to be 1 s
