- An old mistake that has not yet been fixed - if you have built a sufficient amount of anti-missile defense to fight off a battleship, then after its destruction above the base, knowledge of the base's location is not reset and the battleship continues to arrive at it regularly every week until either the base is destroyed or the base will not be defended during ground assault with the help of infantry and armored vehicles. Unfortunately, to verify this fact, more than 10 air defense buildings had to be built, which took up a decent chunk of the base. This means that this method of defense is still ineffective.
- Celatids and Cerebreal fly, but the anti-gravity module cannot be removed from them, since they are of natural origin and these aliens are small in size. Whether it is possible to blind an anti-gravity module from two anti-gravitational glands of these aliens is still unknown, but I would like to try.
- A large harvester is difficult to board because it only has one ground entrance. In this case, a good solution would be to use a dog or rocket tank to open doors and repeatedly detonate the elevator shaft. Undermine until there is no one to approach and then you can begin to capture. if the commander came out, then it is worth putting him to sleep and taking him out of the UFO, otherwise he will simply be blown apart by the next explosion. It is also better to actively use the brain probe to determine the rank of aliens, so that you can capture medics and navigators. Whether there are engineers on this ship is unknown. I also did not find out if it is possible to capture the ship from above through the roof using flying armor or hovertanks, but it is worth trying to check this.
