  • For the Challenge 7: Alien Invasion, you’ll have the usual first wave of Altonians and the second wave containing the last creature. Since all the Altonians are Lancer class in nature, all you need are Saber class servants to burn through them. But take note of the Rider class enemy that waits for you at the end. Make sure to bring an Assassin class servant (i.e. Mysterious Heroine X) to remove that pesky Rider class enemy.
  • Once you reach the second wave, your Assassin class servant will have the best advantage here. However, if you have Star of Artoria, it should make battling this last enemy a whole lot easier. By then however, make sure at least one of your servants has their NP charged. This particular enemy can be quite tanky.
  • If you have Mysterious Heroine X, she should be able to punch down that Daemon waiting at the last area. However, if she doesn’t have her NP, you can also have other Assassin servants such as Jack the Ripper. Or, you can have Okita Souji or Altera to take it down. With that, you’ll have fully completed Challenge 7: Alien Invasion.
