Half Life is a damn masterpiece, from a normal scientist into a sleep deprived (and soon PTSD if he gets to relax a single second) and an 90's approved certified badass because whoopsie doopsie a weird alien man gave you a bigger alien rock then the original alien rock that was ment to be but the adminastrator wanted to be done with the experiment as soon as possible and caused the RESONADE CASCADE!!!.
To Half Life 2 where mankind gets enslaved by an alien race and its adminastrator IS THE SAME ONE FROM YOUR JOB!! pissed right? welp theres a rebelion where some of its main people (or leaders??? idk) worked from the same job as yours! and also the only best ''strong woman'' character: Alyx Vance
and not t omention the sub-plots aka HL: Opposing force, HL: Blue Shift, HL: Decay and not to MENTION the famous HL2: Episodes 1,2 (because theres no 3!!!!! dammit valve!!!!).
Theres also Portal 1 and 2 where it's also in the same canon as Half Life's universe but you check it out yourselfs
anyways these games are awesome and i dont GIVE A ♥♥♥♥!!!!! if the third sequel isnt released (AS LONG AS VALVE STOP TEASING US AND JUST SAY THEY DONT WANT TO!!!!!)

!!!PLAY THE GAMES NOW!!! (OR LATER WHEN YOU GET THE CHANCE TO, THE GAMES ARE CHEAP ASF!!!)
