It looks like this mod adds following items when game starts: 1 power armor mk1, 20 fusion reactors, 100 piercing bullets, 1 personal gun defense.
If you want to remove these, remove the last 7 lines in control.lua:
script.on_event(defines.events.on_player_created,function(e)
local p=game.players[e.player_index]
p.insert{name= 'automated-equipment-#' ..'firearm-magazine'.. '#',count=1}
p.insert('power-armor')
p.insert("fusion-reactor-equipment")
p.insert('piercing-rounds-magazine')
end)
