If you have 95 health, save the large med kit on the ground and return to it after suffering more damage.

Pick up med kits and armor strategically.

As you clear out and move through corridors and rooms, check dark corners for ammo, health, or armor.

Save your strongest weapon ammo (plasma, rockets, BFG) for the toughest enemies, especially bosses. Use a single shotgun blast up close or even just the pistol if there are no other dangers around. For instance, conserve ammunition against weak enemies like zombies. Check the weapon and enemies section of this game guide for details on the best weapons to use against particular enemies.

Practice effective weapons management.

In general, most PDAs-with-code are found in the same room as the cabinet. Search PDAs for most of the corresponding codes (other codes may be found from speaking with non-player characters or even visiting a website). You'll find locked cabinets throughout the game. PDAs include emails and audio logs of current (though probably part of the undead at this point) UAC employees and provide background story and, more importantly, cabinet codes. But on occasion a PDA might be hidden in a dark corner or down a hard-to-navigate hallway. These PDAs look like small red tablets and they're often found-but certainly not limited to-offices on top of consoles or desks.

Personal data assistants are your primary source of information inside the huge UAC complex.
