With the new update out, you want to use a modded gambit so you can get credits early. This allows you to buy a (Recycle modded) Nil weapon at your turret and two HP pots at base without backing, You will also get a steady stream of credits for most of the game until you sell the gambit, 

When laning, upgrade your gambit to level 2 immediately. The lifesteal almost replaces an early soultakers now that it has been made more expensive. Next, get soultakers lvl 1, then a lvl 1 coda blade, and then after that.. Velocity 9 lvl 1. This gives you a range of damage, lifesteal, and attack speed. Upgrade these as you see fit. I usually end up buying coda bladetiers if I don\'t have enough credits to buy a velocity 9 or soultakers. 

Endgame- Rush a deathsrtokes claymore, then buy your other 2 items based on what you want. Claw of Horus, Lobo\'s Chain, and Sword of Beowulf for agreesive playing, Joe Chills and Zeiss Goggles for Crits and extreme squishiness, or Mega Rod for taking turrets and drones more easily.

My last mod is upgraded damage on deathstroke\'s, but if you have a specific item you like go ahead and use it. 

Sorry this is short and only items, but there are many guides for how to play Gasbat. I only wanted to share my idea on laning items with the new update. My in-game ID is jediwood, I hope to see you there!
