Veronica Uplink

Veronica Uplink is an item. Calls a Hulkbuster. Wearing a full Mark 43 it drops the Mark 44 Hulkbuster, and without one (or while sneaking) it drops the standalone Mark 48. The first time, it needs a Hulkbuster Frame. Press M beside the Hulkbuster to become it, and M again to climb out. Use the uplink again while the Hulkbuster stands empty nearby and Veronica takes it back.
