History of Sweeper Bot

The Sweeper Bot is a decoy emplacement in Onslaught, bought with Scrap alongside the turrets and trip mines. It costs 2,000 Scrap to place. Nearby enemies shoot it instead of other targets, which buys the team time, and enemies can break it. A destroyed emplacement loses all the Scrap invested in it.

Upgrades and Scrap

Upgrades cost 4,000 or 6,000 Scrap. Scrap comes from kills by the whole fireteam, but each player spends from a personal wallet, and you can spend your Scrap to upgrade a teammate's defenses.
