They were also able to combine Big Gun and Small Gun to just "Gun".
Which is much better than their original plan of combining ALL PROJECTILE/LASER FIRING WEAPONS to just "Firearms."
But yes, this game derives a lot from Van Buren. So much so that I'd say that Van Buren has gone from debatable/not canon (Fallout BoS) to semi canon (Fallout Tactics).
Let's hope that if they make a Fallout game in Texas that they don't reference anything from Fallout BoS. If any part of that atrocity is ever considered canon (except for maybe city names and some weapons), I will probably end up punching a hole into my monitor.
