Build up to full run speed and speedball towards the left door. With a little luck, Samus will accelerate through the slope tiles and pass under the door.

Entrance condition:

{
  "comeInGettingBlueSpeed": {
    "length": 20,
    "openEnd": 0,
    "minExtraRunSpeed": "$7.0"
  }
}

Requires:

{
  "notable": "Roll Under Door"
}
"canSpeedball"

Exit condition:

{
  "leaveWithMockball": {
    "remoteRunway": {
      "length": 45,
      "openEnd": 1
    },
    "landingRunway": {
      "length": 7,
      "openEnd": 1
    },
    "minExtraRunSpeed": "$7.0"
  }
}
