i like half-life and trains. hows that?im trying to find a mod maker that isnt that complicated.so i can start on my own mod raidiation day.if you wonder what the story line is then here it is.ailians start teleporting into a random city.strangly there all atracted to raidiation .so they get raidiation all over the city. every body starts turning into wierd creatures.but apollo 91 crashed on the other side of the city.its your job to fight your way through the town and reach them.I dont think theres going to be new weapons or enything.
