The monster is available in the store now. I should mention one or two things about its behaviour - it doesn't follow waypoints, but it it will remain roughly within a certain distance of its starting point. The distance is set in lines 92-95 of the script, so change the default figure of 4000 to whatever you want (change both instances of 4000). I would also recommend keeping its territory relatively flat - it can go over hills, but because it's so big, some of its feet will hang in the air on uneven terrain.
The health is set to 5000 - if you change the health (in the fpe or the properties panel in the editor), make sure to change the health[e] amount in line 56 of the script - it's scripted to attack the player if its health drops below the default amount.
The sounds are not included, but easy enough to add. Any 'thud' sound for the footsteps should synchronise automatically, the roar sound (the sound I use is a lion roar from freesfx.co.uk) should be about 2,5 seconds long to match the animation.
