Part of the fun of Wasteland Rebels is encountering new enemy ships and new planets or installations. From time to time, you will come across new worlds and will be told their attitude to the Rebellion. They could already be supporting the Rebellion (in which case you could dock and repair your fleet there), or indifferent, or openly hostile. You will gain victory points for each enemy ship killed and each planet won over to your side; getting 1,000 or more means the Rebellion has won the war. You will also come across trade depots, at which you can repair your ships or buy and sell missiles.
Wasteland Rebels is not a complicated game, but a charming one that will appeal to both Robotech fans and anyone who enjoys a solid text-based game. I had a lot of fun with it, although the gameplay does get repetitive after the 30th or so battle ;) Recommended.
