Samus encounters all seven of the stranded E.M.M.I. units throughout the game. No two of them behave exactly alike, and each encounter gets progressively more dangerous. The first is by far the easiest to get away from. It has a damaged arm and can’t follow Sammus when she escapes up a nearby ledge. The white E.M.M.I. can climb, but can’t go through tight passages, the green can do both, the yellow runs a bit faster, the purple has a bigger field of vision and can use shock waves, the blue can freeze Samus and the red can create explosions.
These abilities makes each encounter slightly unique, but the overall method remains the same. Avoid them at all costs, and attempt to keep out of the yellow cone which represents their field of vision.
There’s no fighting the E.M.M.I.s at first. In most cases, the only thing to do is run. Players who get caught by an EMMI will have a brief window to counter or else they will be killed in a single hit. Once players squeeze past them however, they will have the opportunity to use power from defeated Central Unit hubs to turn Samus’ arm cannon into the more powerful Omega Cannon, giving her enough juice to punch a hole in these dastardly machines. Doing this is how you unlock several of her abilities, such as her Morph Ball. It’s also just really satisfying.
