I’ve played a fair bit of Heroes & Generals. Being a free-to-play game, I expect some grind and slow progression at later ranks — they have to sell those XP boosts, after all — but even at rank 7 (of 22) my XP gains are so miniscule as to turn me off from playing altogether.
Reto-Moto has apparently heard those complaints from more players than just me, and today’s “Furness” update addresses the issue, by doubling the rate of XP gain for characters from rank 4 to 12. Rank 12 is an important milestone, as it allows players to become squad leaders and issue commands to his squad.
Also in the update are five new tanks — three Soviet and two American — new features for generals, camouflage for German tanks, and various UI improvements. You can learn more about the Furness update on the Heroes & Generals site.
