okay I gotta say the two Quake 1 mission packs are.... really pretty good? the level design is pretty great, and the first has a couple new neat weapons (that hammer is hilariously broken but fun nonetheless, and the prox mine launcher, whilst not terribly useful, is pretty funny.). the second mission pack is even better, with lots of interesting tricks, traps, cutscenes(!) and every weapaon other than the axe and shotguns has an alternate ammo you can find that does more damage. :o
