"As most of you may or may not know, Lethal*Agents is sort of a sister-mod to FrontlineForce:Classic in which some of the more basic elements and code will be shared. Almost like working on two mods concurrently. The exception being that Lethal*Agents will be a bit more tactical and will have many additional features that if put into FLF:C would take away from the great game it is. We are planning on having various vehicles, a slew of weapon choices and customizable characters. And if that doesn't set it off, a single player mode is also being storyboarded as I write this. All these features will need to be coded once the FLF:C base is set."
