What changed in this build

Each wave still fields a full 55-alien block, but this version adds elite purple enemies from the early waves onward, UFO bonus targets every 15 to 25 seconds, and a drop table that includes spread, rapid-fire, shield, laser, and extra-life tools. The old arcade shell is still readable, yet the run now has much more target priority than before.

• Clearing the wave is the first checkpoint, but score really jumps when you keep the 2-second combo alive. Each chained kill adds bonus value, and UFO kills stack even more on top.
• Elite aliens are worth triple, and UFOs pay 100 points plus a guaranteed drop. That means target priority matters almost as much as raw aim.

• When the board gets crowded, cut a safe side lane first. Once you can move cleanly, start hunting elites and route toward the next pickup instead of spraying blindly.
• Rapid, spread, and laser are best used to break dense mid-wave traffic. Shield and extra life are not flashy, but they buy the margin that keeps a high-score run alive.
