In anticipation of the release of season two yesterday,
Infinity Ward announced that four popular modes from previous installments would be returning to Call of Duty:
Modern Warfare 2, thereby enhancing the multiplayer interface.
Gun Game appears to have captured the interest of a greater number of gamers in recent weeks than Infected, Grind, and Hardcore.
The free-for-all deathmatch mode, which debuted as a Wager Match game type in Black Ops (2010),

challenges players to secure a circuit of 18 unique firearms and complete them before their lobbies.
Victories must be achieved in this format. Melee-killed players fell one position behind their opponents, leading to an unorganized state of disorder.
Further irrational behavior ensues as the final phase necessitates a Throwing Knife kill for victory.
How to access Gun Game in MW2

The current unavailability of Gun Game baffles players, given Activision’s previous guarantee that it would be available in time for the release of Season 2.
Gun Game, one of three party game modes launching this season, is described in the official blog post as a competition of overall gun prowess.
However, upon initiating the multiplayer client and inspecting the menus for the various modes, Gun Game is noticeably absent.
This implies that the likelihood of its incorporation in a subsequent rotation is high.
Regrettably, Gun Game will remain inaccessible until further notice.

Until the playlist becomes available, we recommend that you regularly verify the modes that are still accessible.
As soon as the mode is selected, you will be redirected to the matchmaking interface where you can locate other participants.
Gun Game is expected to conclude Season 2 on April 11, providing players with a substantial amount of time to appreciate the game during its rotation.
At this time, its continuation beyond that juncture remains uncertain.
Having mastered the Gun Game mechanics in MW2,
it will be added to the rotation momentarily despite being unavailable at this time.
