Description
Run, Think, Defend, and Live.
Clean up the mess the Old Builders left behind.
Explore the world, make weapons, find valuable resources, make a strong base (perhaps, using abandoned bases?), and try to live, before all those things out there destroy you.
Scavenge for supplies, discover new items that can help in your survival, and cooperate with other survivors (more like, friends, if you have any).
Features
Parasites
Hostile beings that quickly adapt and evolve into creatures that can infect ANY living thing around them (except creepers for some reason), so you better do everything you can to prevent the destruction of your world!
Tools and Weaponry
Several items to aid you in survival, from backpacks and simple longswords, to guns, grenades, traps, and others.
A New Dimension(?)
A new dimension (or alternate universe), where the overworld has been taken by parasites a little earlier, with parasites on their last phase of evolution, feasting on what is left. There is some really overpowered loot you can find though. It is not recommended to enter unless you are prepared.
World Options
There are a few options for you to choose in, all with their own features.
I'll be making a survival guide for those who have NO idea what they're doing, so wait up for that!
Also, I did not set up any pre-set keybinds for you, so you will have to set the keybinds up for yourself, I recommend only touching the keybinds for basic controls, the minimap, and the backpack. Sorry for the inconvenience! There are pre-set keybinds in the latest version now!
I talked about world creation types you can choose from, down here!
Default (Boring, isn't it? This won't get you anywhere.)
Lost Cities (Not intended for use anymore, as loot in chests are only intended for The Reflection to use.)
⭐ Biomes O' Plenty (Cool new biomes! A good choice for people who like the basic terrain generation 1.12.2 uses.)
Lost Cities + BOP (Not intended for use anymore, as loot in chests are only intended for The Reflection to use.)
To use these world options, you need to press the "Create OTG World" button in the world list, and pick between these two.
The Wildlands (Cool terrain generation, with huge mountains, volcanoes, and others. Though, doesn't generate any oceans, less structures (just think of it as a hard mode of some sort!) and is incompatible with Biomes O' Plenty.)
⭐ Biome Bundle O Plenty (The BEST choice here. Combines Biome Bundle, an extensive terrain generation mod, and Biomes O Plenty, one of the best biome extension mods out there. There are new places and structures for you to explore as well to aid in your journey!)
More Information down here:
The Reflection, an Alternate Universe, where players were a successful civilization.
But, due to the parasitical infection arriving early in their universe, they went extinct, leaving nothing but a shell of what once was. This alternate universe has the parasites on the last stage of their evolution, only feasting on what is left.
Good part about this place though, is that it features REALLY good loot in the countless amounts of chests left behind by the players who once ruled (grenades, food, weapons, armor, etc.)
(psst, hey, if you really do decide to go in the reflection, i recommend going inside one of the buildings IMMEDIATELY, as they WILL hunt you down relentlessly, which is why it's a good idea to be prepared.)
To access The Reflection, you need a bed, 6 skulls or heads of any mob, and 2 Iron Blocks, and do a certain pattern.
1.) Place the bed
2.) Replace the flooring of the bed with Iron Blocks
3.) Place the skulls around it
4.) Keep another set of these blocks to go back to your regular overworld as once you go in there is no bed to be found

This modpack is intended to be played with friends, as you may struggle to survive by yourself (don't count on my word I'm not even good at my own modpack it may be a skill issue I just have).
To use the resource packs and shader packs in this mod pack, it is a requirement to manually install OptiFine for 1.12.2
You may need to allocate atleast 6-8 GB of RAM to Minecraft to run the shaders smoothly (atleast from my experience).
The gallery is currently unfinished and outdated, with really old screenshots dating back to even before I released this modpack, and so I will finish this soon.
Once I get more gameplay shots while I play this modpack, I will also continue to add pictures to the gallery!
