Crazy OP Siege is a modpack that throws you into a new world where mobs will not give you any breaks. New mob ai and abilities make it so you will have to fight and build to survive. To help in this task, the modpack has a wide variety of powerful weapons, tools, and technology. Resources are generally easier to acquire which allows players to focus on combat and defending their base. Zombies will build up to you, creepers will blow holes in your walls, it's up to you to survive. Recommended to play with friends as it makes the task of defending, building, and finding resources easier.
