"Alien invasion: organize la Résistance"

Reviewed by / Jan 08, 2013

Radiant Defense is a tower defense game set in the radiant universe

If you've ever played other Hexage Ltd games (like Radiant), you already know about Radiant universe: a peculiar glowed graphics and game pace. In Radiant Defense, they've let away pixelated graphics but they've kept lasers and futuristic technology, and of course, alien-invasion theme.

Radiant Defense starring human army commander managing military resources to face hordes of aliens. Thus, your goal is to place (strategically) weapons and modules along the level. If the aliens reach you, you're done: kill them all before they get your position.

Tower defense games aren't worth without a respectable weaponry upgrading system: there are lots of weapons, modules to change aliens direction and many other resources. These upgrades are necessary since complexity increases gradually. However, getting them are not such easy: you'll earn credits as you beat levels and depending on your performance. Economizing resources, being efficient in each level and placing weapons strategically are must-haves to level up.

Entertaining and challenging. What else? Recommendable.

    Could be great but too difficult. Refused to spend money so gave up at level 3. I'd rather it was a bought app right from the start relying on good reviews, rather than it just punishing me and the only way fwd is to spend money - leaves a bad taste in my mouth.

    This game doesn't work well without making in app purchases, but it keeps prompting me to pay with my work account on the phone, not the one I used to install it. This effectively makes it unplayable.

    I have played a lot of tower defense games and I continue to play this one over and over. I really how the developer releases a sequel to this game

    I really like the game but as the it goes on its almost impossible to pass certain levels unless you've paid for the upgrades.

    Really addictive and fun until the 3rd or 4th level.... But once you pay 99¢ to get the money upgrade, its smooth sailing from there. The Devs could update turret AI, which will miss even on slow enemies at close range.
