If you want a place to place another important item, another idea is to somehow put a small ledge inside the tube that comes down from above the slime by the ssg arean. It doesn't really seem to serve any purpose as it is now.
an adrenaline on Q2DM7 would be nice
Anyway, it's fun to suggest changes to the maps to make the gameplay different just by placing items differently and doing minor tweaks to the layout.
And can only join the praising choir of the kryptonite map, I used it in the smackdown tourney and the map had some of the best and most exciting games in the tourney. Well balanced and well designed for the quake2 movement. And just today I played a couble of games on the into oblivion map, fun stuff, a very different map that is a nice change from the standard q2 maps.
I haven't used this feature of r1q2 server yet, but I've been wanting to, to add some extra items on some single player maps for vanilla, for instance.
