Aliens are trying to connect our worlds, to start a massive incursion. They are building a portal, and to stop them, you must kill them.

The blue bar is the portal progress. You can decrease it by killing aliens, but beware, it will increase over time and also speed up.
The red bar is you health, you will lose some, if you get hit or touched by an alien.

Have fun!
