Alien Egg is a fun Idle RPG that takes the basic mechanics that have made this genre so popular and combines them with many others to offer its players an experience with added dynamism and depth, both of which are very interesting additions to this static style of gameplay.
The premise of Alien Egg is simple: an alien invasion threatens to end peace on Earth, and you're the only one who can prevent this catastrophe. You'll start with a limited group of heroes that you can send on different defense missions. On these missions, your role will be reduced to that of a mere spectator, although the game's dynamism and spectacular graphics are still highly enjoyable.
The most interesting part of Alien Egg is when it comes time to create new heroes, since this process basically consists of making your protagonists have children together. The possible combinations are practically endless, and the results are so interesting that you won't be able to stop making your heroes procreate with one another or other players' heroes via the online game mode.
Thanks to its latest expansion, Alien Egg also lets you fight against the fearsome titans of the great anime Attack on Titan.
