Defender

Your real job is the humanoids

Plenty of players treat Defender as a shooter and wonder why they keep losing: the scoring and the survival both hinge on the little humanoids walking the ground. Landers, the swooping aliens, dive to grab a humanoid and haul it toward the top of the screen. If a lander reaches the top carrying one, it mutates into something far nastier. So the priority isn't just shooting landers, it's shooting the ones already carrying your people before they escape. Blast the captor and the humanoid drops; catch it and set it back down for a bonus.

Flying the wrapping world

The planet scrolls and wraps forever in both directions. Thrust left and right to build speed, fly up and down to line up shots, and press Space (or the mobile FIRE button) to shoot. Because the world is bigger than your screen, the radar strip along the top isn't optional: it's how you see a lander lifting a humanoid on the far side of the map while you're busy somewhere else. Read the radar constantly and you can turn and intercept before a captor gets high; ignore it and you'll clear what's in front of you while the planet quietly falls apart behind you.

Fly low, too. The landers do their hunting near the ground, so patrolling just above the surface keeps you at the same height as the fights that matter, and it makes falling humanoids easier to catch. Altitude is for escapes, not for cruising.

Momentum is the other thing to respect. Your ship keeps sliding after you stop thrusting, and turning around means fighting your own speed before you gain any in the new direction. So do not flip direction for every blip on the radar. Pick the nearer threat, finish it, and let your patrol wrap you around to the rest. Panicked reversing bleeds seconds, and seconds are exactly what an abduction in progress does not give you.

Clear every lander in a wave for a bonus. You have three ships, and Defender is famously unforgiving: thrust-based momentum plus threats from both directions is a lot to juggle. Don't fly full speed into unknown territory; feather your thrust so you can react to whatever the radar shows. Keeping even a few humanoids alive through a wave is worth more than a reckless killstreak that loses the whole population.

A rescue, start to finish

Here is the move that separates Defender players from tourists. A dot on the radar shows a lander rising on the far side of the planet with a humanoid in its claws. Turn and thrust hard, and check the strip before you commit, because the world wraps and the short way round might be behind you. Arrive shooting. You want the captor dead while it is still low, since a humanoid dropped from height falls a long way and you have to catch it before it hits the ground. Slide underneath, let the little figure land on your ship, then ease down and set it gently on the surface. The rescue pays a bonus, and the planet keeps one more person worth defending. Pull this off twice in a wave and your score stops looking like everyone else's.

An arcade landmark

Defender was Williams' 1980 hit, designed largely by Eugene Jarvis, and it earned a reputation as one of the hardest games of its era. The trade press barely noticed it at its first show, and then it went on to take in more than a billion dollars in quarters, one of the biggest earners in arcade history. Part of the legend was the control panel: a joystick plus five buttons, including separate controls for reverse, smart bomb, and hyperspace, which flatly terrified newcomers. This version trims all that down to thrust, fly, and fire, but keeps what made the game matter. The horizontal thrust, the wrap-around world, and that tiny radar were ambitious for the time, and the rescue mechanic gave it stakes most shooters lacked: you weren't only scoring, you were protecting something. Jarvis went on to make Robotron: 2084, another famously merciless machine, but Defender is the one that taught arcade players to watch a map while being shot at.
