</>What does Mega Tank do?
Mega Tank supersizes your Vacpack. Instead of topping out after a handful of slimes or plorts, each slot holds hundreds at once, so you can sweep a whole corral, clear a field of fruit, or hoover up a plort payday in one go. Slide the tank size wherever you like, from a comfy boost to a giant hauler, and flip it off any time to snap back to a normal Vacpack. Perfect for big harvest runs, market days, and anyone tired of shuttling back and forth.
</>What is Mega Tank?
Mega Tank turns your Vacpack into a near-bottomless barrel in Slime Rancher, letting each slot hold hundreds of slimes, plorts, or food instead of a handful. Sweep a whole corral, clear a field of fruit, or hoover up a plort payday in a single run, then dial the size back down whenever you like.

</>Common questions about Mega Tank
What does Mega Tank do in Slime Rancher?
Mega Tank super-sizes your Vacpack in Slime Rancher, so each slot holds far more than the usual handful of slimes or plorts. Instead of filling up after a corner of a corral and trekking back to sell, you can vacuum up hundreds of items at once. Clear a whole corral of slimes, a field of fruit, or a giant plort payday, and carry it all in one trip. You set how big each slot gets with a slider, from a comfortable boost to a giant hauler. Flip the mod off any time to snap straight back to a normal-sized Vacpack.
How big can each Vacpack slot get with Mega Tank?
Mega Tank uses a Tank Size slider to decide how much each Vacpack slot holds in Slime Rancher, and it scales from a modest boost all the way up to a near-endless barrel. Nudge it low if you just want a little breathing room over the vanilla cap, or crank it high to sweep entire corrals and fields without a single trip back to the ranch. The setting applies to every slot at once, so your whole Vacpack grows together. Because it is a slider rather than a fixed number, you can tune the exact haul size that fits your session and change it whenever you like.
Does Mega Tank work for slimes, plorts, and food alike?
Yes. Mega Tank grows the capacity of every Vacpack slot in Slime Rancher, so it applies equally to slimes, plorts, food, and anything else you normally vacuum up. Whether you are rounding up a corral of Pink Slimes, stockpiling plorts before a market run, or gathering crates of fruit and veg for feeding, each slot holds the larger amount you set. It does not change what a slot can carry, only how much, so the usual rules about which items go where still apply. The result is fewer trips and far more hauled per run, no matter what you are collecting.
What do the Enabled toggle and Tank Size slider each do?
Mega Tank gives you two controls in Slime Rancher. Enabled is the master switch: turn it on to super-size your Vacpack, or off to go back to a normal tank instantly. Tank Size is the slider that sets how much each slot holds while the mod is active, so slide it up for an even bigger haul, or down for a gentler boost. The two work together: Enabled decides whether the bigger capacity applies at all, and Tank Size decides how big. You can adjust the slider mid-session to find the sweet spot between a roomy stash and a giant one, without touching anything else on your ranch.
When is Mega Tank most useful in Slime Rancher?
Mega Tank is a lifesaver on big harvest runs and market days in Slime Rancher, when the usual Vacpack limit turns collecting into constant back-and-forth. Load up before a plort payday and carry the whole haul to the Plort Market in one go, or sweep a fruit field clean without pausing to dump. It is also handy for corral cleanups, relocating a pile of slimes, or gathering food in bulk for a busy ranch. Anyone tired of shuttling between the range and the sell point will feel the difference. This free mod from ProjectMods simply lets you carry more and walk less.
