Doom/Weapons and powerups
Reference material by Wikibooks contributors. This retains its source identity and is not 411 news reporting.
You will need to find weapons and powerups to assist you in defeating the monsters. You might also need to find switches and/or keys to finish a level.
Weapons
In the following table, Power is the approximate average damage one shot will inflict (in hit points, assuming a direct hit), and Version refers to the game version the weapon first appears in:
S - Shareware version (Doom Episode 1)
R - Registered/Ultimate version (Doom Episodes 2-4)
2 - Doom II

Cyberdemons and Spider Masterminds take only the direct hit damage from a rocket (average 90 HP), not the additional blast damage (average 128 HP) that other monsters suffer.
