Particle Shield is a vibrant fast action tower defense game that takes you to the next level of thought provoking atomic destruction. At your disposal are current and future technologies providing you the ability to unleash the wrath of an accelerated railgun, electromagnetic pulses, prism laser technology, quantum computing and the option to tear the fabric of time and space by generating a black hole! Players must combat waves of inbound radioactive particles while managing a finite pool of resources across 37 engaging stages. Speed is necessary as particles adapt to the player’s decisions and are constantly seeking new paths to their objective. Flexible strategies allow players to overcome obstacles, which enhance the particles, and can create an uncontrollable chain reaction. Rise to the challenge and conquer the elements of Particle Shield.

Optimization of Particle Shield for mobile devices.

Posted by on

I reached a point within development where I planned to start creating the levels for Particle Shield. I say 'planned' because my efforts were redirected towards building the cleanest most efficient base template for my levels. While developing on my beastly rig, I complete overlooked an important factor with my expectation for having this game available on mobile devices.

After scouring the web for optimizing games for use on mobile devices I came to realize that the goal draw call limit is 20-50. Well I can say that Particle Shield was running fine on my computer with around 400-600 draw calls during heavy moments of gameplay. Does this mean the title won't work on mobile? Not if I can help it! I dedicated a great deal of time to address this serious issue which would have crippled the game on any mobile device. At this moment I have the level-grid, UI, and enemies (any number) rendering within 13 draw calls. This was a massive improvement which took some unique design adjustments and the rework of most of the materials used within Unity. Long story short, the game is running like a beast again and I intend to have the first level playable on a mobile device by 3 April.
