That is a .dat edit using arsenal or datedit. Goto orders or technologies and find stim pack and put in a number for "mana".

ya i see, and i changed the energy for stim but it doesnt take any energy ingame, and there is no order for it.

Editing Orders.dat Energy label won't help?

BTW

Is there any way to ADD new upgrade or tech? And anybody knows what techs were in beta-SC and didn't appear in final game? (Roar, Afterburners, Venom and similar thingies)
