$2,730 of Game Dev Assets for $30: The Extreme Game Dev Bundle Is Live

If you are building an indie game in Unity or Unreal Engine and your environment art budget is approximately zero, pay attention. The Extreme Game Dev Bundle from Humble Bundle just went live, and it packs 34 asset packs from Leartes Studios into a single purchase for about $30.

The total retail value of everything included is $2,730. The bundle supports code.org as its charity partner.

What Is in the Bundle?

This is not a course bundle or a software license bundle. It is a massive collection of game-ready 3D environments, character assets, and utility tools designed for Unity and Unreal Engine. Everything comes from Cosmos by Leartes, one of the larger asset creators on the Unreal Marketplace and Fab.

The bundle follows Humble’s classic three-tier structure. Pay more, unlock more packs.

Tier 1 (Pay What You Want)

The entry tier gets you started with four items.

• Vintage Room (a detailed interior environment for Unreal Engine)
• Batch Rename Tool (a utility for organizing your project files)
• Robot Wars CLIMAX (a sci-fi themed asset pack)
• Leartes Gumroad 50% Discount Coupon (for additional Leartes assets)

Tier 2 (~$15)

The mid-tier adds four more packs on top of everything in Tier 1.

• Asian Monastery Refuge (a detailed temple environment)
• Minipoly Series: Modern Island City (stylized lowpoly environment for Unity and Unreal)
• Pivot Manager Tool (a workflow utility for managing pivot points)
• Cyberpunk Sports Hover (a futuristic vehicle asset pack)

Tier 3 (~$30, Full Bundle)

The top tier unlocks all 34 items. This is where the bulk of the value lives. It includes everything from the first two tiers plus 26 additional environment packs.

Standout environments at this tier:

• Stylized Steampunk City and Steampunk Train Station (two complementary steampunk environments)
• Dubrovnik Old Town Environment (a Mediterranean coastal town)
• Fuyoh Cyberpunk Diner Environment (a neon-drenched interior)
• Soviet Apartment Megapack (modular interior and exterior pieces)
• Stylized Paradise Gardens (a lush garden environment for Unity and Unreal)
• Black Forest PCG Environment (procedurally assembled forest)
• Medieval Canal Village and Medieval Stone Temple (medieval themed settings)
• Sci-Fi Complex Lab (a laboratory environment)
• Stylized Medieval Market Fatpack (a full market scene)
• 1950s Characters Bundle (character assets, not just environments)

The tier also includes four packs from the Minipoly Series (Mythic Castle, Race Track, Fantasy Kingdom Interior, and Modern Island City) which use a consistent stylized lowpoly art direction. These work well together if you are building a game with a unified visual style.

Smaller environments round out the collection: Waterfall, Lakeside Village, Verdant Square, Abandoned Industrial Tunnel, Arcade Game Saloon, Artist’s Attic Studio, Mars Rover Simulator, Echoes of the Ancient Gods, Modular Lakeside Village House, Stylized Castle Ruins, and Battle Tank Military Pack.

Who Is This For?

Solo developers and small teams who need environment art fast. If you are prototyping a game or building something for a game jam, dropping in a pre-built environment lets you focus on gameplay instead of spending weeks on level art. Our game jam survival kit covers more free and cheap resources that pair well with asset packs like these.

Unreal Engine and Unity developers specifically. The assets are designed for these two engines. If you are working in Godot, these will not plug in directly, though you may be able to extract and convert individual models. Godot developers might prefer the Learn Godot courses bundle that ran earlier this month.

Developers exploring different visual styles. The range here spans cyberpunk diners, medieval villages, steampunk cities, stylized lowpoly islands, and Soviet apartment blocks. If you are not sure what visual direction your game should take, having a library of environments to experiment with is genuinely useful.

Where Do You Redeem the Keys?

Keys are redeemable on the Cosmos by Leartes marketplace. This is Leartes Studios’ own distribution platform. Some assets are also available on Fab (Epic’s marketplace, which replaced the Unreal Marketplace) and the Unity Asset Store. The bundle keys go through Cosmos specifically.

Is It Worth $30?

At $30 for $2,730 worth of environments and tools, the math is not complicated. Even if you only use three or four of the environment packs in an actual project, you are getting hundreds of dollars of value. The Minipoly series alone would be worth the full tier price if you need stylized lowpoly environments.

The main caveat is that asset packs are starting points, not finished games. You will still need to customize materials, adjust lighting, and integrate everything with your own gameplay systems. But that is true of every asset pack, and having a professional starting point beats building from nothing.

The bundle is live now on Humble Bundle.
