The fearsome Dimensionals have invaded Earth and are gaining the upper hand. As a Centurion Elite soldier, you must get in your favorite ship and take to the skies, driving the alien scum from your planet and all the way back to their home.

EUA is an arcade style side-scrolling shooter, reminiscent of the good ol' days in the Arcade, but with updated comic-book style graphics. Go out for a nice flight in multiple unlockable ships, upgrade each one to your heart's desire, and blast those Dimensionals right out of the air! Travel through three different levels in story mode, or run the combat simulation in Survival mode and see how long you can survive!


- Normal Mode
This is the standard game mode. Whilst playing, you will travel between areas to complete various challenges, such as defeating hordes of enemies within a certain time. During this game mode you will encounter various enemies, each offering their own challenge you must overcome.
- Hardcore / Survival Mode
In this mode, you can play any level previously completed (level 1 is always unlocked). You have access to all technology previously unlocked as well - so you can fully customize your ship for the occasion.
You will have to face waves of enemies, each wave much smarter and more powerful than the last.


The mechanics of Earth Under Attack is what sets it apart from games of a similar setting. If you like games that require strategical thinking then you're in luck. Below is a selection of information on the various statistics within the game.
- Flight
Flying an advanced spacecraft is not an easy thing. There are many various aspects you must consider, such as the speed you are moving and the current level of gravity to name a few.
- Damage
When damage is dealt, a 'base value' is put through various formulas to gain a 'damage value'. The aforementioned formulas provide diversity based on the current condition of your ship. To put it simply - if your ship is in poor condition, is becomes harder to recover.
- Power-ups
At random points throughout gameplay, you will encounter 'power-ups'. If you can collect one of these, it will trigger an automatic 'buff' effect. For example, you would get an instant (temporary) boost to one / more of your stats. Only the rarest power-ups will change your weapon / fire type / fire rate - even then, it will not be a permanent enhancement.

- Enemy AI
Each enemy you encounter has an array of possible AI settings. Needless to say, some will be more intelligent than others. Some of the harder enemies may even use the same technology as you.
