You can read the latest Hellgate London at RPG Vault. It's not very interesting if you've read any of the other previews of the game:
That doesn't mean the first-person title will be uni-dimensional.
Although the demo showcased combat, Schaefer noted that the team is
very cognizant of the need to incorporate a strong RPG layer with a
solid story, character development and quest systems et al. Players who
enjoy collecting items will be pleased to know that there's a random
loot generation scheme designed to provide vast scope for character
customization. An interesting aspect is the ability to modify weapons
so they do additional damage, which can be of different types. The
pistol I saw had one such slot, but I thought I heard other arms can
have more. As for your avatar, you'll be able to choose among "several"
classes, although no specific number was stated.
Modifying weapons? What a revolutionary idea.
