Invaders

The Earth was attacked by the aliens and it is in danger!
But, if you cooperate with each other, you can save it.

Invaders is a cooperative and memory-based game that is played in two phases:

• the "planning" one where you have to deploy your interceptors based on the aliens that are drawn at every turn
• the "invasion" one, where you check how well you did in the planning phase (and where you have few chances to correct your mistakes)

It contains 5 different difficulty levels, each introducing new material and rules.
