According to Eurogamer, most of the purchasable upgrades tie into the game's crafting system, specifically the scavenger bots that you can use to salvage weapon parts and resources scattered around the game world. It's worth noting that these DLC bundles are separate from the micro-transactions in the game's weapon crafting system discovered last week.
Three packs were spotted on the US PlayStation store that'll allow you to soup-up your little helpers, each priced at $4.99. One will increase your bots' capacity, another will strengthen its personality and the final one will speed up its loot collection. Prices for Europe and Australasia haven't been unveiled yet.
Taking to the Dead Space blog, executive producer Steve Papoutsis explained the purpose of the scavenger bots, writing, "Everybody will find at least one of these bots in the game (and there a couple hidden ones to pick up, too.) The Scavenger Bot is an autonomous robot that can harvest resources for you and deliver them to the Tool Construction bench. Resources include stuff like somatic gel, scrap metal, tungsten - materials that you can use to craft into anything you want, like a health pack or weapon part.
"As a replacement for DS2’s credits, resources are a key part of the Dead Space 3experience, and their placement in the game has been well thought out by our game designers. Whether by looting enemies, opening lockers, or exploring the world, you’ll find more than enough resources in-game to fully experience DS3 on any difficulty level.
"The scavenger bot's purpose is to give you an extra edge, since there's a bit of gameplay (and risk/reward) to using him and finding the richest resource caches. You can also choose to download upgrades to the scavenger bot that double his capacity or speed up his trips to the bench."
The other packs available include new weapons and suits for Isaac, as well as those included in special editions of the game. The cost for these varies between $0.99 and $4.99, with the latter being more common. Finally, as is becoming woefully commonplace these days, an online pass will be available for $9.99 so you can play online if you haven't bought a new copy of the game.
