>The Eco-Round ("Economic-Round") most commonly referred to as an Eco or a Save-Round is a money saving strategy that lasts usually one round but may last up to 2 rounds. The Eco-Round consists of buying little to no items. When buying on an Eco-Round it is most common to see a purchase of either grenades or kevlar.
It's a Counter-Strike thing. The economy that lets you buy items every round is a major component of the game. Sometimes you can go full-buy and get fully kitted out, and sometimes you have to play an eco round to make some cash.
