Halo 5: Guardian’s developer, 343 industries, confirmed at E3 2015 the game will contain microtransactions. The game will contain 3 separate types of transactions: cosmetic, vehicle, and gear.
Only cosmetic items will be allowed in Halo 5’s Arena mode, but Warzone will be able to use all 3 types of the microtranscations. Designer Josh Holmes explained to Gamespot how the use of a REQ system will prevent the multiplayer from becoming pay to win.
“Each REQ item costs a certain amount of Energy to deploy. Everybody starts at REQ Level 1 at the beginning of each match and you gain levels based on your actions in the game.” “Capturing bases, killing AI, taking out AI Bosses and killing enemy players will help you level up within the match. The more powerful the REQ, the more energy you need to deploy it”
Although this will hopefully keep it a fair multiplayer, the players with the microtransaction items will still have an advantage, even if its only a slight one. Perhaps 343 Industries should stop messing with something Bungie got right for them.
