"The low amount of Half Life Two or hell any Valve game bots pisses me off but FINE! I'll do it myself" -Literally me last night while getting railed by the enemy team in CS:GO

SO.

In this scenario, you take Alyx Vance's (or anyone you wanna be) at the opening of Half Life 2 Episode 2.

Lore book (extended cut)

You and Gordon eventually escape City 17 via an evacuation train as the Citadel goes critical. The Combine message is successfully transmitted while several Combine Advisor pods escape from the Citadel at great speed. The train you and Gordon were on was struck with a shockwave. The train derailed in the Citadel's explosion. You then woke up and found the Freeman, unharmed, pulling you out of debris and rubble.
