Clock: the in-game time shows on the Stats screen in the pause menu and on every save slot. Pausing stops it, but a checkpoint retry after a death keeps the time you lost: when a death costs a lot, choose End from the pause menu and load your last manual save instead. Saving at tape recorders costs nothing on Easy, so save often. Item box: open it only at the three box rows below. Every other box stays shut, including the one beside each tape recorder and the ones on the ship; the Stats screen keeps the count. The Manage Items option on a boss's retry screen doesn't count as an opening. Healing: every First Aid Med you use counts toward the three, a Strong one included. Always carry one First Aid Med: the wound Ethan takes in the Guest House is healed with one, and a later scripted wound may need one to stop the bleeding; either may count toward the three, so take the two meds in the Guest House Bathroom. Leave every Herb where it lies. Steroids don't count and refill your health, so the two on this route are free heals. With the defense books from run 1, blocking makes most hits cheap.
