Ion Assault HD

This trophy is very tough, and will require a lot of perseverance and practice to acquire. I cannot stress enough the importance of keeping combos going for as long as possible, especially your initial combo at the beginning of your run.

Learning how to deal with each enemy type is integral to success with this trophy. Each enemy has distinct spawn shapes and noises, you need to learn how to recognise these, thus ensuring you can prepare yourself to deal with every situation. Prioritise fire on the enemies that give you the most hassle, you must keep on the move and avoid being bogged down by enemies, all the while keeping a steady stream of score orbs flowing in.
