Gungeon Seed Mod - by Apache Thunder. Source Code to this mod: https://github.com/ApacheThunder/GungeonSeedMod

Features:

• Ability to set custom seeds for seeded runs! Note that certain player actions/choices on a run can impact certain elements of the run.
  But theoretically, if you made the same choices as the player who made the seed, you'd get the same results.

Command syntax:

To set a custom seed use "gungeonseed setseed SEED1 SEED2". SEED1 is the main Gungeon seed and expects a value between 1 and 1000000000.
SEED2 is the RandomIntForCurrentRun seed. This one expects a value between 0 and 1000. Note that setting SEED1 to zero will disable seeded runs.

For best results start a custom seed or new random seed from the Breach with a character already selected.

To start a new seed, use "gungeonseed newseed" to generate a random seed to run on. Write down the seed you see in the console if you want to share it!

To check the current seed you are using use "gungeonseed checkseed".
To reset/disable seeded runs, use "gungeonseed reset".

Note it is recommended to have a completed save file for best results. if the player that started the seed has more or less NPC/item/Gun unlocks then you, then your run may not match the seed the other player played. Floor layout will be the same so long as you unlocked all the NPCs.
