Tay, Hugo actually animated, didn't model, but yes, he took all of his animations with them, if you open up a HI model in hlmv, there are a shit-load of animations, they all had to be remade etc. They were remade, and they are being remade now again by Dirty_J and he is doing a great job, if you go to the HI main site or forums, he put up a video of his new animations. Something cool I think that is being done is new hands, there will be 2 hands, with and without sleeves, and they will have something like 20 skins, so you get model specific skins, be it Nato or tango.
If you guys don't like the maps, make your own (Ha what am I saying, only ~3 of you map here). I personally think the maps look great, but game play isn't that great, its either a camp fest, or a rush fest. With both scenarios abusing the grenades.
All of the bugs are either fixed or are being worked on, wait a few months and it will be better. and BTW: there are plane for a HL2 mod, the more done on HL1 will make it better for HL2.
