well personally id have to say im looking forward to the semi automatic gun and the cool pistols. Id say some attachments like scilencers or bayonets would be cool. I also think some scopes would be nice...maybe a bipod or two for those camping moments or ambush moments were you ban set them up and fire away. stealth kills would be cool too like going into V.A.T.S behind the enemy hiddin and slitting their throut with a knife. looking forward to this game and its beautiful blood spillers.
