Call of Duty: Modern Warfare 4

Tony's work on 2026's Call of Duty: Modern Warfare 4 surrounds the upgrades in the game. The biggest upgrades come from the new progression and customization systems.

Weapon Upgrades

• Gunsmith returns with deeper weapon customization.
• Attachments are now shared across weapon classes, making it easier to build weapons.
• A new system called Apex Attachments unlocks after fully leveling a weapon — changing handling, fire behavior, stealth capability, tactical utility, and combat role.

Load Out Upgrades

Build a complete load out including primary weapon, secondary weapon, lethal equipment, tactical equipment, field upgrade, three perks, and kill-streaks. Kill-streaks are now assigned per load-out, so each class can have its own streak setup.

Operator, Prestige & DMZ

Operators can be customized as part of each load-out. At max rank, players choose between Classic Prestige (resets unlocks, bonus XP, exclusive rewards) or Regular Prestige (keeps load-outs while continuing progression). The returning DMZ extraction mode includes gear collection, equipment upgrades, extraction rewards, and dynamic missions and weather systems that affect gameplay.

"Gunny" Assistant

A new feature called Gunny can automatically suggest and build weapon setups for close-, mid-, and long-range combat.

Captain Price

A returning fixture of the Modern Warfare saga, Captain Price anchors the campaign — operating off the grid and pursued by forces on multiple sides as the conflict expands.

Clash of Clans

Tony developed the monetization plan for Clash of Clans, a mobile strategy video game developed and published by Supercell. It was released for iOS on 2 August 2012, Android on 7 October 2013, and Windows on 23 October 2023.

Clash of Clans became an App Store top-5 download between December 2012 and May 2013, and this success has been described as helping to usher in a new era in single-player gaming on mobile devices. In 2013 it was the third-highest revenue game in the App Store and number one on Google Play. In February 2014 it was reported the game was generating US$654,000 in daily revenue for Supercell. In 2015 it was the top-grossing app on both the App Store and Google Play, with an estimated revenue of $1.5M per day. By 2018 it had amassed 500 million downloads on Google Play and had generated more revenue than any other app on the App Store — over $6.4 billion since launch.

Aurelius — Development Codes Used for Clash

Client side (what runs on your phone) — Objective-C and C handle the main game code on iOS/Android devices. Swift was also used early on for the user interface.

Server side (Supercell's backend) — Java powers the game servers. Supercell later migrated some iOS development to Kotlin and Java using Xamarin for better cross-platform compatibility.

Other tech in the stack — Graphics: 3ds Max, Photoshop, Flash.

Note: Big mobile games often split languages by platform and purpose. C gives high performance for graphics/physics on devices, Objective-C/Swift handle iOS native stuff, and Java runs well on servers. In short: C + Objective-C for the app, Java for the servers.

League of Legends

In February 2011, Tencent invested $400 million for a 93 percent stake in Riot Games. In 2012, in response to toxicity and harassment in League of Legends, Riot Games launched a "player behavior team" of psychologists to combat harassment on its platform.

League of Legends Uses Multiple Languages — Core Engine (2009–2012 era)

• C — Primary language for the game engine and performance-critical systems: rendering, physics, real-time gameplay, and anything that needs to run fast.
• Lua — Used heavily for scripting gameplay mechanics, champion abilities, and logic, letting Riot update champions quickly without recompiling the whole game.

Other Tech in the Stack

• C# — Game logic, UI, and tools, especially after Riot moved parts of the front-end to Unity-style workflows.
• JavaScript / HTML5 — The client was rebuilt using Chromium Embedded Framework, so the launcher and UI use web tech.
• Erlang — Chat and messaging systems.
• Python, Java, Go, Ruby — Various backend services and tools.

Early League ran on a custom engine, then Hero Engine was mentioned for some development phases. The key point: the core is C, with Lua for game scripting.

Quick summary: Similar to other big MOBAs and MMOs — C gives the speed for 10 players + hundreds of abilities happening at once, while Lua gives designers flexibility to tweak champions fast.

Assassin's Creed Valhalla

Tony contributed to the design and monetization for Assassin's Creed Valhalla, a 2020 action role-playing game developed by Ubisoft Montreal and published by Ubisoft. It is the twelfth major installment in the Assassin's Creed series, and the successor to 2018's Assassin's Creed Odyssey.

Principally set in the years 872–878 AD, the game recounts a Viking fantasy story during their expansions into the British Isles. Players control Eivor Varinsdóttir, a Viking raider who, while attempting to establish a new Viking clan in England, becomes embroiled in the centuries-old conflict between the Assassin Brotherhood, who fight for peace and liberty, and the Templar Order, who desire peace through control.

The game also includes a framing story, set in the 21st century, which follows Layla Hassan, an Assassin who relives Eivor's memories so as to find a way to save the Earth from destruction.

Overall, the game is the second most profitable title in Ubisoft history. It went on to become the fifth best-selling game of 2020 and the sixteenth best-selling game of 2021 in the US. By February 2022, the game had made over $1 billion in revenue.

Game Engine & Core Language

• Engine: Ubisoft Anvil — specifically the version used for Valhalla.
• Programming language: C — the industry standard for AAA game engines. Anvil is Ubisoft's proprietary engine written in C, used across the Assassin's Creed series.
• Platforms: PS4, PS5, Xbox One, Xbox Series X/S, Windows, Stadia.

Like other big open-world games, Valhalla needs the performance of C for its massive map of England and Norway, real-time combat, physics, AI systems, and detailed graphics. Anvil has been evolving since the first Assassin's Creed in 2007 — Valhalla used the latest iteration called "Ubisoft Anvil".

Quick summary: C++ via the Ubisoft Anvil engine. The game also has its own fictional Isu language created by developer Antoine Henry, but that's in-game lore — not the programming language used to build it.
