As suggested in Nojarq's topic these are the options you can buy with one boost:
Price: 1 boostTrails
Kevlar + Armor
VIP on TAB
VIP Player Skin
Rank on the forum
Admin Player Skin
Your vote is weighted on map choose
Price: 1 boost (each)Jetpack
You can buy VIP package or you can select to buy any of the VIP Extras. In any case, you can enjoy what you chose in the spawn of 30 days.
Let me know if everything seems about right or it still needs to be adjusted somehow.
