When it comes to games, the Android offerings in App World have been less than stellar, but Sinister Planet by Neolithic Software is a fun and smooth shooter that is worth the download.
According to the developer, Sinister planet is:
Slick and fast-paced arcade shooter.
Asteroids meets Sinistar.
Blast your way through wave after wave of relentless alien hoards. Five increasingly challenging planets to destroy. Ship upgrades and increasingly frantic gameplay will keep you coming back for more! Beautifully rendered asteroids and retro-style graphics will transport you back to the heyday of arcade classics.
* 25 waves of aliens
* Multi-touch 360 degree shooting
* Power-ups galore!
* End of level boss to destruct the planet!
* 60fps action
* Global high score system
* Bonus "challenge" waves
* Awards and achievements
Your objective is to attack and destroy a series of alien worlds, the ultimate of which is Planet Sinister. To destroy each world you'll attack the planet surface and take out the power grid protecting the planet's core.
Upgrade your ship
To aid you on your quest, you'll have the opportunity to upgrade your ship's weapon systems, by means of collecting power-ups (in Arcade mode) or collecting gold (in Battle mode).
As you progress through the waves, you're going to need those upgrades as more deadly enemies are introduced. Old-school afficanados will recognise some of the aliens based closly on such classics as Galaga and Defender (take a look at the Pods/Swarmers!). Upgrades available include R-Type style extra laser pods to double or triple your firepower, ECM attacks (aka Smart bombs), turrets for multi-touch 360 degree shooting, and more.
Collect the Gems
To progess each wave, your task is to collect the gems produced when blasting the asteroids (think: Sinistar). Don't worry, the asteroids won't hurt you, but you'll be faced with a different challenge - your enemy ('Roamers') just love to grab those Gems too - so make sure you reach them first - and beware! Shoot them quickly, or they'll be transformed into a much more dangerous foe (think: Defender). Lose all your gems and you'll have to fight the remained of the waves from 'Witchspace' with nothing but chaotic Mutons attacking from all sides.
As a welcome respite from the hard-core destruction, you'll get the chance to gain some bonus points by completing the challenge waves. Aliens will fly in formation around your ship while you attempt to do a complete wipe-out (think: Galaga). It's not easy, but getting the right upgrades will aid your task. During these waves your ship gains temporary indestructibility.
Sinister Planet has been carefully crafted over many months to provide the perfect challenge of difficulty vs playability. As you improve, the game will grow harder to meet your challenge. So far only one player has destroyed the Planet Sinister - may you be the next?
