A downloadable mod
Popo is a mod that makes new things come out of IDPD and Van portals. The further you get, the more chaotic everything becomes.
On a normal run you should see new IDPD spawns begin somewhere around Palace.
Not much more to it than that, and I don't want to really spoil anything, so I hope it adds some variety and fun to your game!
Also, a good thank to Blaac for IDPD Tank, sprites, and ideas!
NTT beta is required for this mod to work, find it in the NT Discord's #co-op_buddies channel description. https://discord.gg/nt
Extract the popo folder to your mods folder and type "/load popo" in in-game chat.
