THQ has released Star Wars: Trench Run, a new game for the iPhone and iPod touch. It costs $4.99 and is available for download from the App Store.
Reliving the climactic battle sequence of the original Star Wars movie (Episode IV: A New Hope), Star Wars: Trench Run puts you in the cockpit of a Rebel X-Wing as you take on the mighty Galactic Empire. The game starts out high above the Death Star where you must dogfight with Imperial TIE fighters before heading into a trench, where you must avoid cannon fire, dodge obstacles and stay out of Darth Vader’s sights long enough to fire your proton torpedos into a thermal exhaust port. A successful hit means setting off a chain reaction that will destroy the Death Star and deal the Empire a crippling blow; a failed attempt will doom the rebel base and the entire Rebel Alliance.
Features of Star Wars: Trench run include Force Power, which lets you slow down time and increase your agility to dodge obstacles; special effects like lighting, shaders, explosions and life-like models; hidden features; original music and sound effects; accelerometer controls; chase cam and cockpit modes; multiple difficulty levels and more.
The game requires the iPhone or iPod touch running iPhone OS 2.2.1 or later. Special graphical features have been added for the iPod touch second-generation, iPhone 3GS and other future devices.
So, “lighting” is a “special effect” now? It would be hard to see anything without lighting.
Actually you don’t need lighting to see the scene, it can be all drawn with lighting switched off and using pre-lit textures. Don’t forget that this is OpenGL ES, not real life ![]()
Dynamic lighting isn’t normally used on mobile games, it’s too compute intensive as mobile GPUs accelerate pixel operations, not transforms and lighting.
