From the description in the Store:
Space Shooter X is a shoot'em up (shmup or STG) and an action pack "bullet hell" game where your mission is to shoot the enemy ships and win battles against big bad bosses and travel through the galaxy.
Inspired by Raiden, the old school Japanese shooters, there are tons of unique enemy ships and bosses, each equipped with specialized weaponry and ability.
While the game is easy to handle, you need more than fast reflexes to master the game. To survive in each level, you need to recognize attack patterns and use different power ups at appropriate time against the correct enemy.
Upgrade your ships with several levels of lasers, spread bullets, homing missiles, torpedoes, speed power and powerful bombs. The power ups stay with you until you die and you will accumulate more power as you collect the same power up.
The graphic is an exhilarating visual treat, with cool music and sound effects providing intense experience for hardcore gamers and casual gamers alike. In addition, you can submit your core to both global leaderboard and you country leaderboard. So you know who's the top players are in your country.
There are tips and how to strategies in the About/Help page where you can learn what each power up does, how to gain extra live for free and how to get full power- ups without having to wait for it to appear.
Get it now, you won't find a better space shooter, asteroid, shmup, shoot'em up or bullet hell game in Windows Phone Store.
Here's Space Shooter X in action:
Getting going, the name and country are important if you want to check your national leaderboard (see later)...
In action, backgrounds and aliens are pixel perfect and silky smooth. You control your craft by dragging - and this auto-fires your main gun - it all works brilliantly and only occasionally was I stymied by my thumb obscuring a vital bit of the screen.
Bottom left and bottom right are controls for releasing smart bombs (one shown in action, above, left, a hail of missiles that destroys everything on screen) and power-ups...
The 'bosses' are big and bad and the sooner you can take them out the better! (right) one extra power up for rating the game should see plenty of people help Space Shooter X rise in the Store rankings....
Although I happily blasted away for a good ten minutes, if you want a really long blasting session or a really high score then you'll need to go freemium, though the amounts asked are reasonable and most people will only end up spending a pound or two. Nicely pitched.
Top in the UK today - woohoo! (right) the Help screens are exemplary, showing what all the power ups and bombs doo, plus pages of tips and advice. Well done to the developer.
A top notch game for Windows Phone and highly recommended. You can download Space Shooter X for free here.
