I'm pretty sure the fumes emanating from Indie Royale's perpetually whirring bundle factory have finally gone to the shadowy conglomerate's head. April Fools, after all, was days ago. Or perhaps... no. Perhaps the joke's on us. Maybe Indie Royale spent the entire year secretly offsetting every calendar in the world by a couple of days. Now countless schedules are in tatters, nations are falling, and no one knows when Game of Thrones will be on again. Or maybe Indie Royale just needed a catchy title. At any rate, Defense Grid: The Awakening, Alien Zombie Megadeath, Explodemon, and Hack, Slash, Loot are up for grabs. Astro Tripper's the bonus this time around. Details on each after the break.
Defense Grid, of course, is a delightful tower defense classic, and it's well worth a look if you for some reason turned a blind eye to it all the other times it was on sale - say, because you'd gone temporarily blind. Alien Zombie Megadeath is sadly not about an aged metal band's rather unconventional return to the limelight, but a fusion of bullet hell shoot-'em-uppery, platforming, and the ability to spell "death" correctly mostly make up for it.
Explodemon, meanwhile, is a snazzy throwback to the tough-as-nails platformers of yore, and Hack, Slash, Loot's a retro roguelike that's not quite as mean as the other retro roguelikes. Adam was quite taken by its roguish charms. Then there's Astro Tripper, which does the whole spaceship shmup thing competently - if not in any spectacular fashion.
So then, you are now informed. Do with that knowledge as you will. I make no judgments.
