ACTS.DAT (TFTD)
TFTD's ACTS.DAT file is somewhat different to that in UFO.
The acts are:
offset act 0 Probe Mission 1 Interdiction * 2 Resource Raid * 3 Infiltration * 4 Colony Expansion 5 Surface Attacks ** 6 Floating Base **
* These are not tried in some zones as they are not realistic, e.g. abduction in Antarctic.
** Colony Supply Missions, Alien Surface Attacks and Floating Base Attack 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):
