SM2: Every Call of Duty Player's Dream Game

Introducing sm², a massive modification for Call of Duty: Modern Warfare 2 which adds new maps, weapons, and more.

Since the inception of the Call of Duty franchise, players have longed for the day when an all-encompassing title combining the most desirable content and aspects of the previous installments would release. Although we've seen similar concepts from Activision in both Call of Duty Online and Mobile, these titles have been strictly limited to a target audience, unavailable to the vast majority of players.

Over the years, various client modifications, such as IW4x and Plutonium, have unarguably improved upon the experience which the respective clients are based upon; but nobody has attempted to craft the premiere Call of Duty experience - until now.

What is sm²?

sm² is a client modification for Call of Duty: Modern Warfare 2 which boasts all-new content and features on top of "revamped" gameplay systems. The primary objective of sm² is to create the ideal experience for every Call of Duty player with an exponential and ever-growing amount of options.

Highlights of sm² include:

  • 100+ weapons upon release, each with attachments and camos
  • 24 Perks, including both original and returning abilities
  • Modern Warfare 3 Strike Chain (Pointstreak) system, with additional streaks
  • Integrated party and voice chat systems
  • Currency system similar to that seen in Black Ops, including Wager Matches
  • Dedicated melee weapon slot, as seen as Modern Warfare Remastered
  • Native music player, as seen in Black Ops 3
  • Unique Progression systems
  • Gameplay ping system, as seen in Modern Warfare (2019)
  • Native Controller support, including Aim Assist

At the time of writing, sm² is currently not released and there is no announced release date.

Home - sm²
sm² is a modded Call of Duty client based off the MW2 engine with all new features, weapons, perks, streaks, maps, QOL changes and more, all designed on top of our revamped gameplay to create a fun and balanced experience.


One of sm² biggest aspirations is an arsenal of over one hundred weapons, each of which with its own attachments and unlockable camos. Currently, only a handful of the weapons planned to be available upon release have been announced; but even now, it's a star-studded lineup, to say the least.

Although a list or total count of Multiplayer maps has yet to be revealed for sm², the Developers behind the mod have already shown the potential of the modification with fan-favorite maps from the franchise being ported to the Modern Warfare 2 engine. Alongside the maps natively available in Modern Warfare 2, you can expect to see many more, including Firing Range (Black Ops) and Overwatch (Modern Warfare 3).

Progression & Unlocks

Unlike similar Call of Duty client modifications, sm² will not feature an Unlock All ability for players to gain access to its content. Instead, a revamped Prestige and Grand Master Prestige system has been implemented for those who wish to grind through the ranks. On top of this, a Credits system will allow players to earn and unlock the content of their choice at any given time.

With these systems in place, sm² is aiming for a traditional progression system which rewards players for activity while recognizing that many players would rather play their way without grinding unlocks. Play your way.
