Lo people
Zak Jr and I are co-opping through Quake 2.
It's gotta be one of the finest father/son combo's I've found so far. Clearly Q2 is a classic, and clearly it is old. But it also plays beautifully and scales well on bog standard kit. It's still hard, it's still dizzyingly complex in places, and we both get utterly lost sometimes.. but ...
it
is
splendid.
If you still have Q2, install it on two pc's and get it on the network.
