The launch of Call of Duty: Modern Warfare 3's second season in 2026 has ushered in a fresh wave of adrenaline-fueled combat for players across the globe. This season introduces a structured series of weekly challenges that will unfold over the next eight weeks, offering a continuous stream of objectives and rewards. Each week, a new batch of 21 challenges becomes available, spread across the game's three core pillars: the frenetic Multiplayer arena, the cooperative undead nightmare of MWZ, and the sprawling, high-stakes battlefields of Warzone. The inaugural set of challenges is now live, bringing with it a significant prize: a powerful new conversion kit for the formidable Longbow sniper rifle.
Week 1 Challenge Reward: The JAK Tyrant 762 Kit
By successfully completing any five of the week's challenges—whether focusing on one mode or mixing and matching across all three—operators will be rewarded with the JAK Tyrant 762 Kit for the Longbow. This conversion kit represents a radical re-engineering of the weapon's core, modifying the receiver to chamber potent 7.62 BLK ammunition. The trade-off is dramatic: each shot now deals a staggering 17% more damage, but this comes at the cost of halving the rifle's effective range and bullet velocity. This attachment fundamentally alters the Longbow's identity, sacrificing its legendary long-range precision for devastating close-quarters punch.
In the fast-paced skirmishes of Multiplayer, this raw power boost surprisingly makes no difference to the weapon's Time-to-Kill (TTK), rendering the attachment a curious side-grade at best, and a straight downgrade for traditional snipers. However, the landscape shifts dramatically in Warzone. Here, the enhanced damage profile transforms the Longbow into a reliable two-shot elimination tool, a terrifying prospect for any opponent caught in its crosshairs. For aggressive players seeking a high-handling, high-impact sniper for urban combat, the JAK Tyrant kit is a compelling acquisition. For purists who value reach and precision, this week's reward might be one to pass on.
