Introduction
Ion Assault HD is a tough, rewarding and extremely fun twin stick shooter. If you’re after an easy 100% I suggest you look elsewhere, this game requires a fair bit of dedication and practice to play successfully. On the other hand, if you’re after a gaming experience that delivers superb gameplay, the addictive 'one more go' mentality and some trophies to be proud of, then look no further. For some reason, it would seem this game is somewhat of an unknown amongst the masses, which I have to say is a real shame - if you’re on the fence whether to give this game a try, I highly recommend taking the plunge.
Walkthrough
Step One - How to Play & Survival Mode
First things first, from the main menu go to ‘Help’ followed by ‘How to Play’. These videos and instructions prove useful to understanding the gameplay mechanics and techniques you need to be using when playing the game. Once done you have two options, Campaign Mode or Survival Mode; I highly suggest starting with the latter. Tackling Survival Mode and ultimately earning "The will to live" trophy will better prepare yourself for obtaining the "High Score Hunter" trophy in Campaign Mode.
Step Two - Campaign Mode
With the experience you’ve gained in Survival Mode, it will make beating Campaign Mode and earning the "High Score Hunter" trophy far less daunting and infinitely more achievable. Throughout Campaign Mode you can earn the various miscellaneous trophies available, however these really needn’t be worried about, as your primary concern is aiming for the elusive 5,000,000 + points total. Any miscellaneous trophies you may be lacking after beating Campaign Mode can be earned in literally a few minutes if you actively seek to achieve them.
