The BP50 is a new assault rifle introduced during Season 2 of Call of Duty: Modern Warfare 3 and Warzone. The new weapon is not unlocked from the beginning, but here is how players can easily get the BP50 during the season.
How to Unlock the BP50 in Modern Warfare 3
Modern Warfare 3 and Warzone players can get the BP50 assault rifle by completing Sector B7 of the Season 2 Battle Pass. The rewards of the Battle Pass are divided into sections on a grid, and finishing a sector will unlock access to adjacent sectors near it.
Each sector in the Season 2 Battle Pass requires five Battle Token Tier Skips to complete. Taking the shortest path to the assault rifle means it will take 20 Battle Token Tier Skips to reach and finish Sector B7. Starting at Sector B1, players can take the path on the left through Sectors B2 and B4, or on the right with Sectors B5 and B8. Either method will cost the same.
One important aspect is that players do not need to purchase the Season 2 Battle Pass to unlock the BP50. The weapon is a free reward on the Battle Pass track, and all players can earn the weapon during Season 2 with no additional purchase.
Players can receive Battle Token Tier Skips by earning XP across Modern Warfare 3 multiplayer modes, the Zombies mode, or Warzone Battle Royale modes. Some events later in the season may award additional Tier Skips, or players can buy the BlackCell Battle Pass Bundle to instantly receive 20 Battle Token Tier Skips (25 for PlayStation owners). It is more expensive than the regular Battle Pass but comes with more rewards.
