ACTS.DAT

Contains information about which acts and with what priority in respective zones the aliens are going to try. Each of the twelve zones has seven possible acts which sums up to a total of 84 bytes.

Each month, after rolling on ZONAL.DAT to get a location to target, the computer rolls on ACTS.DAT to determine what mission to perform there. Every act thus selected has its priority set to zero and, if that was the last act with non-zero priority for that zone, the zone's weight in ZONAL.DAT is also set to zero. The aliens will perform one act per month from February until June 1999 (inclusive), then two acts per month until ACTS.DAT and ZONAL.DAT are exhausted in April 2001. From May 2001 onward, the only new missions generated will be Alien Supply, Alien Terror and Alien Retaliation (which do not use these tables).

The acts are:

offset	act		
0	Research 	
1	Harvest 	*
2	Abduction 	*
3	Infiltration 	*
4	Base 		
5	Terror 		**
6	Retaliation	**

* These are not tried in some zones as they are not realistic, e.g. abduction in Antarctic.

** Alien Supply, Alien Terror and Alien Retaliation are generated separately, rather than through ZONAL.DAT and ACTS.DAT. These values are normally unused (Supply doesn't even have one).

At the beginning of a new game, ACTS.DAT looks like this (in hexadecimal):
