What Game Engine Does Payday 2 Use?

Ever wondered how Payday 2 manages to pull off those epic heists and intense shootouts? A big part of the magic comes from the game engine it uses. Game engines are like the brains behind the game, handling everything from graphics to physics. Payday 2 uses a special engine called the Diesel engine. It’s not as famous as some others, but it’s super important for this game. Let’s dive into what makes this engine tick and why it was chosen for Payday 2.

The Diesel Engine: A Deep Dive

The Diesel engine, developed by Overkill Software (the creators of Payday 2), is a custom-built engine. That means they didn’t just pick something off the shelf; they made their own specifically for their style of game. Think of it like building a car from scratch instead of buying a pre-made one. This allows them a lot of control over how the game looks, feels, and runs. This engine isn’t just used for Payday 2; it’s also used in other Overkill games too.

Why a Custom Engine?

Why go to all the trouble of building your own engine? Well, it gives developers a huge amount of flexibility. When you use a pre-made engine, you’re working within its rules. With a custom engine like the Diesel engine, the developers can make the game work exactly the way they want. This is crucial for unique gameplay elements and performance optimization. In the case of Payday 2, Overkill needed an engine that could handle a lot of players, complex environments, and lots of action happening at once. They wanted a tool that was perfectly fitted for their needs, so they made one themselves.

Key Features of the Diesel Engine

So, what makes the Diesel engine special? Let’s look at some of the features that have impacted Payday 2:

• Multiplayer Focus: The Diesel engine is designed with multiplayer in mind. This is super important because Payday 2 is all about playing with your friends. The engine handles multiple players, lots of enemies, and tons of in-game interactions smoothly, which is important in any heist game.
• Level Design Flexibility: The engine allows the developers to create large, intricate maps. Each bank, store, and jewelry store in Payday 2 is a carefully designed level. The Diesel engine makes sure that these places feel real and are fun to explore, and most importantly, allow for different strategies and approaches.
• Physics and Interactions: While not as advanced as some engines, the Diesel engine does a good job with in-game physics. Objects react believably, and there’s a lot of interactive elements within each level, like walls that can be blown through or doors that can be kicked open.
• Customizability: Because it’s their engine, the developers can add specific features and tweak things as needed. This allows for ongoing game updates, new content, and fixes without being limited by an engine’s established framework.

Limitations of the Diesel Engine

While the Diesel engine has worked well for Payday 2, it’s not perfect. One of the big limitations is that it’s not as polished as some of the more widely used engines. Here are a few things to consider:

• Graphics: The Diesel engine is not as visually impressive as some modern engines. While the game looks good, it might not have the same level of detail as games built on more advanced technologies, because the focus was not on very high graphics, but on the gameplay elements and mechanics.
• Resource Intensive: The engine can be demanding on computers, particularly when many things are happening at once, such as large number of cops, explosions or many players in one spot. The engine was built for what the game needed, so not for highest graphics but for maximum gameplay elements.
• Limited Tools: The tools and resources for developers are not as extensive as for popular engines like Unreal or Unity. This might have made it more challenging for developers at times.

Comparing Diesel to Other Game Engines

Now, let’s see how the Diesel engine stacks up against some popular game engines:

Unreal Engine

Unreal Engine is one of the biggest names in gaming. It’s known for its high-end graphics, extensive features, and tools. Games using Unreal Engine are generally very visually striking and can be used for a variety of games, unlike Diesel Engine which was made only for their type of games. It is also very easier to use compared to Diesel Engine for the developers because it offers a lot more support and documentation.

How Diesel Differs: The Diesel engine doesn’t have the same graphical power or range of features as Unreal. However, Diesel is more tailored towards a multiplayer experience like in Payday 2, while Unreal is good at a lot of different styles of games.

Unity

Unity is very popular too, especially for indie developers. It’s known for its ease of use and large library of assets. Many mobile games and smaller indie games use Unity due to its user-friendliness.

How Diesel Differs: The Diesel engine is specifically built for more complex, multiplayer oriented gameplay, while Unity offers a broader range of applications. Unlike Unity, which is a generalist engine, the Diesel Engine is specialist.

Source Engine

The Source Engine, famously used by Valve in games like Half-Life and Counter-Strike, is another influential game engine. It’s known for its detailed physics and fun gameplay. It’s not as complex in features as Unreal or Unity, but it’s very effective.

How Diesel Differs: Both the Source Engine and Diesel Engine are built for multiplayer action. However, Diesel is very specific to the Payday type of gameplay, while Source is designed for various styles of gameplay. Diesel also lacks the polish and features of Source, but makes up for it with its in-house tailored style.

The Impact of the Diesel Engine on Payday 2

The engine selection has influenced the game in many ways. Here are some key areas where the Diesel engine is evident:

Gameplay Mechanics

The engine has a direct impact on the gameplay. For example, the way shooting feels, the way your character moves, and the way the cops respond all come down to how the engine is programmed and designed. The engine allows for complex AI behavior for the cops, different types of enemies, as well as the ability for players to use a large variety of weapons and gadgets. These elements all help create the signature Payday 2 experience.

Level Design

The Diesel engine allows for large, multi-layered environments. The heists in Payday 2 are much more than just a single room; they involve complex layouts, multiple paths, and even hidden areas. The Diesel engine allows for developers to create these intricate environments, adding to the replay value as every heist can have a different approach and strategy.

Performance

While the engine can be demanding, the team at Overkill Software has worked hard to optimize it for Payday 2. They focused on ensuring the game runs well on most computers, even when lots of things happen at once in game. However, it can still struggle sometimes on low end computers or in areas where the action is very intense.

Is the Diesel Engine Still Relevant?

Payday 2 came out in 2013, which is some time ago in video game terms. So, is the Diesel Engine still relevant today? The answer is a mixed one. While it’s not on the same level as modern engines in terms of graphics and features, it has served Payday 2 well. However, in future games or installments of the Payday franchise, Overkill might find it more useful to move to a new engine, given the graphical and performance advancements in modern engines like Unreal Engine 5.

The Diesel engine, while not perfect, has allowed the developers of Payday 2 to create a fun, unique, and enjoyable experience for millions of players. It’s a testament to how a custom-made engine can be a great tool for a game that has a specific vision and style.
