I just reinstalled Star Trek Armada for Windows 10. Long-time fan. But I cannot get past level 4. The game just ends. Not sure why. I complete the level, but then it just goes to the next campaign (Klingon from Federation). Anyone else have this problem? I also cannot zoom in or out. I tried the ctrl + up and down arrow keys, but nothing happened. Thanks for the help!
Mission 4 is Dark Omens, I believe. This is the last map of the Federation campaign, so yes, it should lead you onto the Klingon Campaign. This is intended behaviour.
Its been some time since I played the original but, I believe to zoom, the keys were the plus and minus keys on the keypad.
