Product Description
Radiant HD
Blast your way through asteroid fields and enemy forces
Radiant HD
Switch between weapons in game by tapping on your ship and choosing your desired weapon
Radiant HD
Spend credits to upgrade your weapons
Radiant HD
Oppose the evil Supercreep and his legions of 8-bit followers

You are First Space Sergeant Max Blaster, fighter pilot and archenemy of evil space creeps everywhere. Sharp-witted with even sharper reflexes, it's up to you to dodge asteroid fields and decimate aliens attacking from the top of the screen. Blast forward and take a stand against the odious Supercreep and his synchronized hordes to stop them from destroying all humans in this challenging, colorful space shooter.

Blending the Classic and Contemporary

Radiant HD gives you arcade shoot 'em up goodness the way you like it, blending retro tropes like limited movement (right and left only) with modern takes on the genre such as upgradeable weapons and on-screen power-ups.

Battle on one of three difficulty settings through a three-part story with over 100 levels. Collect power-ups, upgrade an impressive arsenal, and dodge your foes to stay alive. Destroy over 10 huge bosses like the Planet Cruncher, the Hunters, and the Supervisor. The challenges may be steep, but the power at your disposal is staggering.

Big Guns for a Big Threat

Blasting asteroids, groups of baddies, and larger enemies can reveal credits in 25, 50, and 100 increments. Collect these and every few stages you'll get a chance to spend them on upgrades to your guns. Each weapon can go up to level 10, and the rate of fire and number of rounds fired with each shot will improve as you buy upgrades. Invest wisely in each of these interchangeable extensions like you would in a role-playing game to smooth out your weaknesses and prepare for any challenge that may come your way. They include:

  • Vulcan Cannon, a traditional blaster that fires rapidly but is fairly weak
  • Bio Blaster, a small, slow shot that deals enormous damage upon impact
  • Plasma Gun, a well-rounded weapon with moderate speed and firepower
  • Disruptor Laser, a powerful but slow laser that carves through hordes of enemies
  • Seeking Missiles, homing rockets that steer toward the nearest creep
  • Smart Gun, small, rapid shots that fire straight then curve toward the nearest enemy
Grab Passing Power-Ups

Radiant HD doesn't just ask you to dodge rocks and return enemy fire; it rewards you for your destruction and smooth moves with helpful power-ups. Like collecting credits, other power-ups may appear when you destroy your enemies. Unlike credits, though, these goodies will sate your need for instant gratification. They include:

  • Energy Shield, a guard that covers the front of your ship and absorbs painful projectiles
  • Megablast, a screen-clearing blast that wipes out all visible enemies
  • Time Freeze, a convenient time stopper that lets you gun down your foes while they sit helpless
  • Various gun power-ups, an instant increase to the level of the weapon indicated on the power-up icon

5.0 out of 5 stars Wonderful! February 26, 2012
Verified Purchase
A excellent galaga clone with an added story and different upgradeable weapon types. One minor annoyance is that there is no in game info on what each weapon type does. Playing the game and trying each weapon out is the way to learn.

5.0 out of 5 stars Classic arcade meets witty storyline February 26, 2012
Verified Purchase
Most of the low ratings for this app seem to concern problems with somebody's device, not the quality of the actual game itself! Firstly, I can tell you that this gem runs perfectly on the HTC Merge. Secondly, it provides an entertaining and at-times satirical narrative for classic arcade hits like Asteroids, Centipede, and Space Invaders. Stringing these games together with an unobtrusive electronica background and colorful pixel mashups of the original arcade graphics, the storyline and dialogue comes right from the pages of those old Atari manuals--you know, the B-movie descriptions of scenarios and worlds that simply couldn't be conveyed on screen back in the day, so the developers had to write them in the user guides? The storyline is hardly ingenious, but its lighthearted jokes at the player and CPU, combined with such entrancing visual quality, gives Radiant HD a high replay value. Reviewers who can't appreciate these inside jokes and, for that matter, the addictive simplicity of the games themselves, will be disappointed in the apparent shallowness. For someone like myself, however, it's a breath of air amidst the crowd of cartoon, commercialized apps.

5.0 out of 5 stars Love the game February 26, 2012
Verified Purchase
This game is incredibly simple, yet fun. I thought that it didn't save at first because there was no options menu that you can pull up to save games midway. After playing and stopping and coming back to the game I realized that it saves and you just start off where you finished. Changed from 4 to 5 stars now. Love this game. Reminds me of arcade games when I was a child.

5.0 out of 5 stars Fun Arcade-Style Shooter September 3, 2012
Verified Purchase
If you enjoy games like Space Invaders or Galaga you'll feel right at home with Radiant HD. This is a very fun arcade-style space shooter. The controls are really easy, the ship fires automatically all you have to do is move it side to side to avoid enemy fire and to collect coins and upgrades. At the end of each wave you can spend the money you earn to buy weapon upgrades. The are a number of different weapons ranging from lasers, missiles, to spread-shots.

In between each wave you get a couple lines of dialog to keep the story going. There is a lot of humor in the writing and it can be a lot of fun to see the back and forth between your ship and the aliens. Visually the game looks pretty good. Enemies glow with bright neon colors and so do each of your weapons.

It would have been nice to a little more variety in the levels but other than that this is a really nice game. If your looking for a simple, fun, relaxing game, look no farther than Radiant HD.

3.0 out of 5 stars Fun for a bit March 1, 2012
Verified Purchase
There are some good things about this game. It plays great on my Kindle Fire. Autofire is a good thing. I can't imagine tapping the fire button for hours on a touch screen. It has a decent storyline. Also, contrary to what a reviewer said, even though the update says it has to uninstall, you do not lose your progress.

The multiple weapons seem like an interesting twist. That is, until you figure out that all you need is the disruptor laser. If you spend all your cash upgrading it, you can destroy anything. That lowers the replay value.

Love the retro feel, but since firing is automatic it makes the game boring very quickly. Half the strategy on eighties shooters is knowing exactly when to fire. Read more
