FSX. Love fighter aircraft but still haven't tried TacPac? VRSimulations has just announced the Superbug X is no longer a prerequisite for purchasing the TacPack, however in order to fully enjoy all the features the TacPack has to offer, VRS strongly recommends using the product with a TacPack-Powered aircraft. A number of TacPack powered aircraft are already either completed or in the final stages of development. For more information on this, check out the VRSimulations website via the source link. Thanks to ADX reader NarutokunJB for the tipoff!
