World of Tanks: Hammer Base

Free Tiger I Hammer Tank

In August 2016 there were five ops titled Hammer Challenge I-V which lasted a couple days each. If the player successfully fulfilled their goals, the player was granted free Tiger I Hammer tank and a garage slot with 100% trained crew. Challenges I & II required player to earn 5 points, challenges III & IV to earn 10 points, and challenge V to earn 15 points. These ops were only available for tanks ranging in tier from III to X. Tiers I and II did not apply to these ops.

Rules for earning points were: * Gain 1 point for winning a battle * Gain 1 point for placing in the top 5 XP earners * Lose 1 point for losing a battle

Additionally, each individually completed op yielded some sort of reward on its own: * Hammer Challenge I - repair kit * Hammer Challenge II - 2,000 silver * Hammer Challenge III - 1 day Premium account * Hammer Challenge IV - 1,000 XP (gold stars) * Hammer Challenge V - final reward (Tiger I Hammer tank and garage slot)
