This pack contains everything you need to make an entire game (all of these packs are also sold separately). Poly count was kept to a minimum with optimization in mind. Here is a rundown of the Mega Pack's contents.
Goblin Army PackContains 4 different army units, each with their own style of clothing, armor and weapons (Bomber, Grunt, Basic Soldier, Elite Soldier) with 3 levels of detail for optimization. All the models are rigged and each have between 9 and 15 unit specific animations included. Also contains a fully rigged Goblin General, bringing the total to 13 rigged models (59 rigged models if you include all the skinned animations).
NPC PackContains 2 male and 2 female NPCs. One of each with a full body, and one each with a half body. Full bodies can be used for main characters or roaming NPCs, and half bodies for shop merchants (behind counters). All 4 models are rigged, and have 3 basic animations included (nod head yes, shake head no, and shoulder shrug I don't know).
Siege Weapons PackContains a Ballista (Crossbow) with a seat and a Catapult. Both come with firing animations.
Buildings PackContains 6 different buildings, all with shopfronts and their own unique style traits and shop signs with images to help identify them (not words that limit you to one language).*A Forge/Blacksmith with smoke stacks and mine carts filled with iron ore.*A Lumber Yard with a mill and unprocessed lumber.*An Engineering/R&D building with a lightbulb (universal sign of an idea) and spare parts and gears.*A Hydroelectric Power Plant with power cables and transformers.*A House with a seating area and fire pit, and a garden with vegetables and fruit trees.*A building template with a few different signs in case you want to expand using the same materials and style of architecture.
