The technology tree in Science and Industry is the pool of upgrades available to your team when you vote. At the start of a match, you will be equipped only with the briefcase and colt. Once your scientists are settled into their lab, voting commences and it is your job to choose the research path for your company. There are five branches of technology your company can research: Weapons, Implants, Armor, Devices and Process Upgrades. Each branch is made up of tiers and to progress to the next tier you must first vote for a lower-tier upgrade.
It is important to understand what each upgrade does, and how it will affect your next vote. The outcome of a game can be greatly affected by the choice of research your company makes. Study the techtree, keep an eye out for fellow team mates voting choices and also your opponants voting strategy, making a bad voting decision could cost you greatly!
