this game is so awesome considering its free
the tilegen thing is a bit silly i think but its cool that you can create maps this easy, even tho theres not much room for altering stuff unless you use hammer
i like the sdk additions aswell.. but it would be nice if valve fixed some of there other sdk's first before releasing this
Loaded the Alien Swarm hammer up witch should use the same file storage system (.vpk) as l4d2 hammer and it was almost instant
while my L4d2 hammer takes from 10 to 15 mins to load..
i know it its properly partly the size of the game files that causes this but would still be nice if it was a tad faster
oh yea.. and the Alien swarm modelviewer dont work properly for me
