Chikyuu Kaihou Gun ZAS marks another Board Boosters milestone as our first speedrun from the space-ship shooter genre. This Game Boy title is infamous for pushing the console to its absolute limits as one of the few games on the platform that utlizes frame blending to display parallax backgrounds. Paired with the large number of sprites on the playfield at a time makes Chikyuu an incredible feat of Game Boy programming!
As with many schmups, a significant portion of the game scrolls automatically, which means the speedrun finds many other unique ways to save time. Picking up power-ups and point collectibles off the playfield can drop frames off the counter. Destroying oncoming attackers early and even withdrawing your ships options can reduce lag, saving the runner even more precious seconds.
Power through five stages, complete with mid and end-level bosses, and save the planet Earth!
