In the main campaign, sometimes I receive out-of-mission (i.e., randomly sumbling upon sites of interest) scientific targets specifying invalid instruments. I found these in the Victora Crater in this game version.
Examples:
- an atmosphere target requires the MICRO tool
- a rock target requires the EMS tool or RAD tool
- some targets require multiple tools, such as
- EMS/EAS atmosphere, but they sometimes work with EMS (passive) or EAS (active) only.
- APXS/RAD a rock, but of course APXS works only
Most of these two or three- instrument scientific targets appear in the regular missions as well (for example, the APXS/RAD a rock).
