Well, for starters, the "Obsoletable Equipment" page talks about having to research Grenade Launchers. AFAIK, this info is from an older version of the game? I'm used to playing 2.2, and i don't remember having to research them. There are also references to Tachyon weapons, which [correct me if i'm wrong] got replaced by Particle Accelerators. I'm ready to edit things to the current standard, but i don't want to step on anybody's toes. I guess i first need to sort out which version the wiki is meant to cover?
