And 7 hours on Blue Shift also searching for secrets, and it might take you a little bit less, because it took me 24 hours to beat Half-Life. And i can say that opposing force is almost as good as Half-Life. I recall game installs taking anywhere from fifteen minutes to hours, depending on the game. For Half Life 1, I recall it being like a 30ish minute process on my home PC? I also had a slow computer and played Half Life and the associated mods at 15-20fps for years, so my install might have been slower
So, by 4 × t 1/2 to 5 × t 1/2, the serum levels are reduced by almost 94% to 97% of the peak level. In other words, the entire dose you gave is almost gone from the body by 4 × t 1/2 to 5 × t 1/2. Assume that a dose is given repeatedly and regularly, and that serum levels during one dosing interval are averaged for the sake of discussion.
