This is a Strider from the game Half-Life² I just love these things though they're quite hard enemies...but they make funny sounds when they die

To everyone who doesn't know:

A Strider is basically what you see on the pic with VERY long legs (It's over 30 feet high when it's standing straight...) Its most used weapon is the Pulse Turret (the thin thingy pointing out of its 'mouth'. More dangerous is the Singularity Cannon (the big one in its middle) which can even destroy walls or whole buildings. But if you have a good hiding place, a crate full of rockets and a rocket launcher relatively easy to defeat

Needed about 3 hours to finish it. Done with ink and paintbrushes (size 12, 2 and 5)
