Quoting Tom R.
I'm planning on doing countless WWI moc and I had an idea... After intense Gas shelling on the British front line none survive... At least that is thought... In one part of the trench a lone Tommy wakes up. What does he find? Guess...
Quoting Andrew Knox
To survive being gassed, the best thing to do is put your head in the ground and wait for it to pass, which can lead to hallucinations...or can it? That sounds like a great plot device.
