For once I'm not gonna bash zone okay. This is going to be a real legit suggestion idea thread. Please, no drama.
So my idea is basically the opposite of a pay to win system. So you buy a gun lets call it a v.1, meaning it's fresh and new and it has not been upgraded. So you basically work with the weapon until you get to the next upgrade. And then there's like 1-3 upgrades total (the more upgrades a weapon has the less powerful, and vice versa) and upgrades shouldn't always have better stuff. Maybe if a gun gained damage it gets less mobility. And the way you work up the points to get to the next upgrade is by getting kills or destroying alien ships. And you're probably wondering, people will start boosting to get the upgrades. But imagine this system with the "move to respawn" idea. And ofc since zone wants money there could be a way a player could buy a fully upgraded version of the weapon. The price should be 2-4x more than the original. I mean, it's different from ol West and era. I think.
