I've had a few requests for ports of dm_tower_arena_v2, most of which were for hl2ctf. Thing is I don't play hl2ctf, and I don't know the gameplay at all, so I ended up enlisting some help.
Special thanks to Snillor, who handled majority of the porting work on this map. The item/entity placement, and most of the changes/additions to the layout of the map are thanks to him. I really only oversaw the process and cleaned up any problems.
Also, apparently the storm in dm_tower_arena_v2 lagged more than I thought... so I've optimised the storm in this ctf version slightly - should offer improved performance (neccessary because the map is bigger)
