Scramble is a small Black Mesa style episode with a bit of different gameplay than typical Half-Life maps. Collect all 5 Lambda Nuclei and reach the exit. Please do mind the headcrabs, they can be nasty. Scramble is essentially a hybrid prototype for a much larger Half-Life mod that is coming soon.
Scramble mod for Half-Life. Unzip to the Half-Life directory to install.
It`s mod is strange but idea is very good
Goodluck for modding!
