No. Gmod is only for PC
No you can not
simply press E on the keyboard next to the cars door :) i play gmod add me on steam username is kayden
yes but it is illegal and you can't download addons steam can also trace you if you play gmod without steam for prolonged periods of time so I recommend not using a pirated copy of gmod. it is also likely that you can't play online based on other reports of pirated copies and besides nobody likes a pirater
no. gmod is only for the pc.
