Overkill is great, I've enjoyed a lot of games, actually lately spent about equal time playing regular Xonotic and Overkill. The gameplay is very straightforward and simple, but a lot of complex and fun situations happen for teamwork because of the spawn system. Everything works as expected without any gagdets and gimmicks that can confuse players and is great with players of all skills. Plus, it uses the same physics and maps so it's very easy to switch between the 2. These days I prefer Overkill for public play over regular Xonotic, and prefer regular Xonotic for duels and pickups, I have no trouble playing both.
I don't see what the fuss is all about, if people complain because it is a mod, then Minsta is just the same in the sense that it uses none of the weapons from regular game and is one shot kills and I don't see people whining about it being in serverlist and such, it's basically a mod just as Overkill is a mod. If anything, Overkill should be be included in the game (if it's not already) because it's obviously very popular and kicks Minsta's ass.
