BROMAXXING is a small modpack I made for friends. Expect a few small inside jokes and less polished picks.

The pack includes larger mods such as:

Aetherworks
Better Combat
Biomes O' Plenty
Blazegear
Blood Magic
Coffee Machine
Cola Bottle
Colossal Chests
COP - Create
Corpse

Cuckoo Clock
Dungeon Crawl
Embers Delight
Embers Rekindled
Endertrigon
Farmer's Delight
Gnetum
Gradium
Hornets
Ice and Fire
Ice and Fire: Poison Dragons
Le Fishe Au Chocolat
Lycanites Mobs
Midnight
Most of an Allosaurus
Mowzie's Mobs
Nightfall
Poison Dragons
Portalium
Quark
Recurrent Complex Volts
Rolling Giant: Oldest View
Spartan Fire
Spartan Poison
Spartan Too

The pack has an Exploration focus, allowing players to build whatever base they want and specialize in whatever mods they choose. 

The modpack has a unique design my friend and I came up with:

The player starts the game as usual, with mobs from the Lycanites Mobs mod allowing you to get many materials
Then the player can tamper with whatever mods they want [Mob taming, machines, SCP hunting, etc.]
A few mods such as the new Midnight dimension, Ice and Fire: Dragons, Mowzie's Mobs, and and more add unique exploration encounters to give you some unique equipment for the new final boss overhaul
The Ender Dragon from vanilla has been Very highly buffed so the fight is much harder even with the modded gear

If you're not familiar with modpacks and want to play with your friend(s), this modpack is a great start. It generally offers:

Over a hundred new mobs

A whole new dimension

Dozens of new biomes

Machinery far beyond your average redstone

Better performance

Included shaders

Good server performance

Multiple new structures and dungeons

Magic systems and spells

New gear sets/tiers

Some horror elements occasionally

New, overhauled combat and weaponry system
