Sequel
There is a sequel named half life 2.
It's really popular, has good reviews and has a funny physics engine (source.)
Also, Dr. Kleiner says "Oh fiddlesticks, what now?" when a sound effect can't be found.
Demo
There's a demo named "Half Life Day One".
You can get it on mod DB.
This demo is commonly run on the CVMs BY ME!!!!!!! (bruhfromcollabvm)
It somehow got leaked years ago, and became a very talked about game before the full game even released.
HOLY CRAP!!! A GAME WHERE YOU CAN SHOOT THINGS??
Yep, that’s half life for ya.
Go buy it at steam.
