Dark Sector Reference

Warframe is a game based in part on Digital Extreme's earlier successful project: Dark Sector. These are the features in Warframe based on aspects of Dark Sector.

From the game:

• Tenno: The name of Warframe's player faction comes from Hayden Tenno, the protagonist of Dark Sector.
• Excalibur: Around mid-game of Dark Sector, Hayden stole a power suit/proto-Warframe that looks simliar to the Excalibur frame.
• Excalibur Proto: A skin that was introduced in Update 12.6 highly resembles Hayden Tenno's suit.
• Nyx: Nadia Sudek/Nemesis, the one who infected Hayden Tenno in the first place, used a power suit/Warframe that has a Nyx looking helmet.
• Infested: The Technocyte Virus plays a big part of the game and is what Hayden is infected with. This is similar virus that created the Infested. 
• Glaive: The Glaive is a weapon commonly used in Dark Sector alongside Hayden Tenno's sidearm. It is created with his infected arm and obtains upgrades regularly throughout the game.
• Grineer: The Grineer are present in the 8 minute trailer of Dark Sector as an enemy. While not in the game, the Lasrian Troopers look similar to them.
• Lotus: The Lotus symbol is seen throughout Dark Sector, including in the game's logo. It is also the game's icon and in game organization. Also, during the cutscene at the end of the first mission in Dark Sector, you are told that "The lotus is something truly beautiful, yet it flowers amongst that which is dead." This seems fitting of for Lotus, as she is "blooming" in the center of a "dying" race, the lost Tenno.
• Dark Sectors: Dark Sectors are locations in the solar system which can be claimed by clans. They bear the same name as the game Dark Sector.
• Clan Emblem: The default Clan Emblem is the logo of Dark Sector.

From the trailer:

• Jackal: An armored quadruped vehicle in Dark Sector similar to the Jackal on Venus, but looks like a Grineer-like version.
• End-Mission Animation: In the trailer, Hayden Tenno is seen stepping into the drop ship the exact same way a warframe would. The room is exactly the same and also features the hanging Corpus-like suits in the background.
• Burston: The Grineer-like enemies used this rifle in the 2004 trailer, but not actually in the game.
• Solar rails: Mentioned by Hayden.
• Lotus Quote: Some things Hayden says are also said by the Lotus (e.g. "there are Grineer marines everywhere.").
• Escape pod: The same one used in missions in Warframe.
• Aklato: Dual Latos are clearly seen when he shoots the Grineer.
• Sounds: Grinner used to make the same voice lines as the lines used in Dark Sector. (before they were changed to speak Grineer).
• Corpus-like Suits: Can be seen at 6:39.
• Stalker: Begins with whispers almost identical to the Stalker.
• Trinity: Can be seen at 2:05 in this trailer, albeit with a different glow pattern on the face plate.
