Apocryphal texts recovered from cultists of the Order indicate that the Gun and the Bullet are linked somehow.
|This potent artifact indicates mastery of the second chamber.
Any who enter the Gungeon are doomed to remain, living countless lives in an effort to break the cycle.
Effects[edit | edit source]
- Grants a heart container.
Notes[edit | edit source]
- Chief Master - If the player has Alien Sidearm and any two Master Rounds, the Alien Sidearm has a much larger magazine and cannot be charged, but becomes fully automatic and the final two shots in the magazine are fully-charged shots.
- Master's Chambers - Each Master Round the player carries permanently unlocks the Chamber Gun's mode of its respective floor. Reloading the Chamber Gun with a full magazine cycles through the unlocked modes.
- Master Rounds are one of the necessary materials to unlock shortcuts. When they are used for this purpose, the Tinker will take away one Master Round, and therefore remove a heart container from the player.
- Master Rounds will not appear if the player takes any kind of damage during a boss fight, including falling into pits and other kinds of damage not inflicted by the boss itself.
- Master Rounds can be dropped, which will remove a heart container. When they are picked up after being dropped, they will add an empty heart container.
- Master Rounds give one piece of armor to The Robot.
- Master Rounds can't be sold to the Sell Creep, except in a special room in the Hollow, where you need to give him a Master Round and two Items to enter the R&G Dept..
- Master Rounds can't be stolen by the Resourceful Rat.
- Acquiring five master rounds in a single run unlocks the Lead God Achievement and Super Hot Watch.
- The achievement can still be unlocked via Boss Rush or by acquiring duplicate Master Rounds with Clone. For example, if the player gets four master rounds, then dies with Clone and respawns in the Keep of the Lead Lord, the achievement will be unlocked as soon as they get another Master Round.
- It is not necessary to pick up the Master Rounds to unlock Lead God (although there is no reason not to pick them up). The achievement will still unlock if the player beats the five bosses flawlessly without picking up the Master Rounds that they drop.
- Killing a secret boss without taking damage counts toward unlocking the achievement.
- There is a sixth unused Master Round.
Trivia[edit | edit source]
- The Chief Master synergy is a reference to Master Chief from the Halo video game series.
- Altered: King Bomber - Lil' Bomber used to be able to synergize with the first Master Round for the synergy King Bomber, but was removed because it was too easy to obtain.
