I could be persuaded...
I hate you guys [005 et al] for being in agreeable time zones.
So I finally got my hands on the infamous Alpha leak of Doom 3 from back in [circa] '02 - I figure it's been long enough and i've purchased Doom 3 at least twice now [in different formats].
It certainly is interesting, A possibly different [more action focused] direction than the game we ended up with.
It has a pretty cool feel to it and it does feel different to the full game - There isn't really much to play through and certain enemies like zombies don't really do much - although they do get up again and continue pursuing you after you plug them full of bullets.
One thing that was interesting / different is that the enemies speak actual [gutteral] english, commando zombies say things like "I smell fear".
Apparently this is from when Trent Reznor was still on the project and the game structure seems to back that up - there are audio folders labelled as 'nin' and such. I actually prefer some of the sounds here as some stuff in the full game gets annoying when you hear it over and over. Weapons sound more 'meaty' for example.
All in all, an interesting play-through and I personally would have preferred a game in this style with the polish of the final game, rather than the attempted scare-fest we did get.
