Orokin derelict void treasure room
Apparently, Venus was terraformed by dumping giants amounts of coolant onto its surface, which ended up turning its heat-scorched surface into a frozen wasteland.You are also sent to missions on Earth to stop the Grineer's attempts at terraforming Earth for themselves by destroying their machines being used to poison the jungles. Earth itself was turned into a gigantic jungle to preserve the cities underneath the flora. Corpus outposts on Venus and Mars are set in snowy areas, strongly implied to be due to the Orokin, while Phobos is now an arid environment all have breathable atmospheres.The devs eventually just added the codex fragments on the ghouls as drops from the ghouls themselves, due to complaints. Furthermore, Ghoul plagues return every so often, and so do the bounties related to them. Unlike the other events, though, the enemies introduced with the bounties contined to spawn even after the bounties ended, and they have the blueprints for the weapons as part of their drops. Ghoul Bounties are a Downplayed example - they offer different rewards from normal bounties and are the only way to fill out the Codex entries on ghouls, but they are only around for a limited time.While some of them (Survival, Excavation, injecting and defending toxins from the Cicero Crisis) remain in the game in some form, many of the original, unique maps and gameplay modes, and ALL of the unique dialogue, lore, and character interactions, are gone, with no way for new players to experience them (short of brief text blurbs in the Codex.) To a lesser extent, played straight with the events themselves.These were part of the Founders' Package during the earliest parts of the game's beta as part of the deal, now that those packages are no longer available, those Primes are out-of-reach for any player that doesn't already have one (and DE has confirmed they WON'T be coming back). Played dead straight with the very first Primes: Excalibur, Lato, and Skana.Specters of the Rail alleviated some of the frustration with the overhaul to Void, since players can still use existing Relics to farm vaulted items, but you're out of luck for items that were vaulted before the change, and the Relics can start to become Too Awesome to Use over time as the supply diminishes. Items do get brought back occasionally, but at a much slower rate than items going away in the first place, and they only come back for a month at a time. Unlike the event weapons, these weapons can be obtained by any player with persistent farming for the blueprints and components (or, for the lazy, they can just buy them from other players) however, starting with Volt Prime's release, the oldest Primes get shelved with each new Prime Access. Prime weaponry are similar to the above, being upgraded, gold-and-white trimmed versions of existing weaponry.Fortunately, the anniversary weapons return each year, and old event weapons have slowly been making their way back into the game through Tactical Alerts, Sorties, and Baro Ki'Teer's wares. These versions are flatly superior to their normal versions, so it can miff some players that they may be stuck with inferior versions of their favorite weapons. Once the relevant event to acquire these weapons passes, they're gone, and barring a future event by the developer, new players can never obtain them. There are elite, one-of-a-kind versions of various weapons (Dex for celebrating the game's anniversary, Wraith for supporting Grineer during events, etc.).Temporary Online Content: As the game is beta and thus under constant development, all of the below is subject to change at the whims of the developers for now, there's a significant double-whammy:.High-tier Grineer melee troopers can teleport close to get the drop on you, and Grineer Captains can do this to the player - often to dump them in a room with a Heavy Grineer or in the middle of a pack of shotgunners.for a completely different warframe: Ivara. The developer suffered much complaining from certain quarters, considered the facts, then added the scanner bypass ability back into the game, as an official "augment". This has since been patched so that Switch-Teleport still triggers alarms if its use runs a line through detection areas. When Spy missions were first introduced, Loki's Decoy/Switch-Teleport allowed cunning players to bypass 98% of the alarms, scanners, and trip-wires.
