The controls are very easy to use, but if you dislike them for whatever reason, they can be changed to your liking. The game does feature a bit of physics will help and hinder you depending on how you manipulate it. While you orbit Earth firing at the seemingly endless enemies, you will notice that each missed shot curves back due to the Earth’s gravitational pull. This can be used to barrage enemies from above them, but if you miscalculate your bullets will come crashing back down into Earth inflicting great damage.

The game incorporates some tower defense elements as you’ll be able to acquire additional ships that attack the incoming threat. You are also able to upgrade your own ship by increasing speed, fire rate and the effective blast area. Aside from upgrading your own ship, you are able to increase the Earth’s health which will be needed as the game progresses.


The audio for Earth Defenders HD is as you would expect. It is similar to the arcade classics Asteroids or Space Invaders. The firing sound effects are akin to the same period as they are similar to most classic arcade or Atari games.


The graphics of Earth Defenders HD were also reminiscent to the classic arty styles of Asteroids and Space Invaders. They are the 8 bit style that has been coming back in the new neo-retro style.

Down to the Nitty Gritty:

My appeal to Earth Defenders HD was the curiosity of playing a new take on the classic Space Invaders game. Being a huge fan of retro games and the neo-retro games that have been coming out lately, it was only fitting to give this game a shot. The game’s difficulty at first seemed really easy, but it quickly grew significantly harder as I felt I was doing more damage to the Earth than the invaders were. After realizing this I began selective firing and did far better. The upgrades were very helpful as they are necessary to play the game to the fullest. The audio and graphics were similar to the arcade games of the 80′s, but with a game like this, there is no point trying to reinvent the wheel. The game is well worth your time if you are a fan of retro games. If you’re in the mood to play a new rendition on a classic, then give Earth Defenders HD a try.
