Counter-Strike 2 has released an update that makes one of the biggest changes in the game's modern history: and no-one saw this one coming. Valve has changed how reloading works, so that when you reload, any ammo remaining in your current magazine is lost. And players are not happy.

"When you reload in CS2, the leftover ammo in your magazine is dumped back into an essentially endless reserve supply," says Valve's blog post on the change. "And so the decision to reload has never offered significant trade-offs—in a safe position with enough time, you might reload after firing a single bullet, or half a mag, or after firing down to empty, and the rest of the round would be unaffected.

"We think the decision to reload should have higher stakes, so in today's update reloading has been redesigned. Now, when you reload, you'll drop the used magazine and discard all of its remaining ammo. Instead of 'topping off' your weapon with a few bullets, a new full magazine will be taken from the reserves whenever you reload."

There’s also now a new HUD element, a small bar under the bullet count that empties when you shoot: so it's easier to tell at a glance roughly how much ammo you've got left. You also have a new mag count.

The change comes with a bunch of buffs and nerfs to individual guns' ammo counts: ThourCS2 went through and worked out the exact numbers.
