Besiege's war machines would only appear in a history book if a bored schoolchild scribbled them in the margins - little pencil machines bristling with blades and flamethrowers whirl through stick figure armies leaving trails of red Biro. It's a physics puzzler about piecing together pistons, hinges, blades, bombs, saws, spikes, cannons, wheels, wings, and other bits into death machines able to annihilate armies, crush castles, and conquer kingdoms. You can buy into the alpha now.
Cor, look at that diorama-y art style! If it weren't poor netiquette, I'd embed this 6MB gif of a spinny blade machine mincing knights.
In these days of ironic physics, I do still enjoy the simple novelty of physics-based puzzlers where any kookiness is the result of a horrible accident as something I've made tears itself to pieces. I imagine that'll happen a lot in Besiege. And I especially enjoy the examples in this here trailer where a machine going terribly wrong still manages to complete its objective:
You can buy the alpha, which currently has 15 levels and a sandbox mode, for $6.99 (£4.60). It's currently laying siege to Steam Greenlight too. Should it breach the barrier, developers Spiderling Games plan to add Steam Workshop support to share siege engines.
