This Map Labs theme takes the What if…? approach. Authors were asked to just nudge reality (well, the Half-Life games) just a bit and explore what might have been. Wait, is there a Map Labs multiverse now?

Here are the 7 alternate timeline maps received, enjoy!

One Room, Bone Room, Two Rooms.

Following a proven pattern (not including the Half-Life: Alyx One Room challenge), Map Labs has unpredictably expanded to Three Rooms with this Test Tube competition! The entrants were technically limited to three rooms, but there’s also some trickery at work in some of the maps here. Enjoy the 21 entries!

This release combines two Map Labs Test Tubes (short challenges). Unfortunately, one of them only received one entry so it was combined with the larger Test Tube.

A Place in the West, as the title suggests, simply asked authors to build a map based on the popular comic Half-Life: A Place in the West, which depicts life in America under the Combine.

The Wrap-Up Two! – much in the vein of The Wrap-Up! – allowed mappers to choose any previous Map Labs theme and enter. Finish an abandoned project, remaster a previous map, or make a brand new map; all were acceptable as long as the map fit one of the Map Labs themes. Nine maps were submitted.

Enjoy this double feature!

As a follow-up to the successful Tune (a 24-hour Atom), the Map Labs folks expanded the challenge for this Test Tube. Plus – as the title confirms – there’s a twist: entries must be based on TWO songs!

This unique challenge allowed mappers to tidy up an unreleased or unfinished map – or make a totally new one – for any of Map Labs’s previous themes [even at the time, that was a whopping 23 themes to pick from!]. But being a Test Tube, time was really limited – this challenge only ran for 10 days.

Here are the wrapped-up and entered maps – enjoy the solid 19 maps in The Wrap-Up!
