Sorry if I'm spamming uploads here, but I've been on a spree of building new bots and upgrading old ones recently.
The AlphaStrike is a modification of an older rail spider I had which was simply called "ALPHA". if you've seen me in game the chances are I was using that bot. I was inspired to make this by a sled/walker hybrid one of my friends built. It's a really cool combo and I haven't built one in ages, so here it is.
AlphaStrike is extremely mobile, functioning well as both a sled and a walker if you use keyboard controls. It's an excellent backline artillery bot and good for sniping at the weakspots of opponents, or crippling and killing fliers. However, it is very bad at close range combat as you would expect from a rail walker, so avoid getting into brawls.
If you want to get the bot, just search "Alphastrike" on the factory.
EDIT: There's a non-cosmetic version as well for those who don't have the wolf legs or carbon thrusters.
