* The [[http://www.youtube.com/watch?v=N3Yaj86m9vM PS4 trailer]] shows a Frost, Nyx, and Ash rescuing a newly awakened Excalibur in an excessively awesome (and entirely possible in-game) display. The high point is [[spoiler: Frost freezing Captain Vor leading the capture attempt with a massive ice blast and stepping aside, allowing the Excalibur to slide in and chop him in two with a spin attack.]]
* The gameplay trailer where the first three Warframes and Rhino slaughter their way through a Grineer army.
* The first time you do a charged melee attack on a poor Grineer. It really sets the tone for the game.
* The first time you slide on your knees down a ramp while blowing away multiple enemies. Yeah, it's one of those kinds of games.
* The first time you manage to defeat a Stalker on your own and/or get a blueprint of one of his weapons.
** This one has been made extremely difficult, as the Stalker is able to deal incredibly high damage and dispel or ignore all ability effects that don't cause direct damage. Rhino's Iron Skin and Loki's and Ash's invisibility won't save you anymore.
** The first time you defeat ''any'' of the enemies that come after you like the Harvester or the G3 is also this.
* The 'Operation Slingstone'' event, that tasked the players with destroying massive Grineer warships, was the first one that could actually be lost. The developers later admitted that they expected the players not to completely succeed in it. Instead however the community managed to beat it completely.
* The ''Gradivus Dilemma'' event. It was an unprecedented event where player actions would actually decide which faction would control Mars, tied into in-character roleplaying posts by Alad V and Sargas Ruk, with the result that the event had record participation from players, along with the greatest sense of player participation and enthusiasm.
** Credit should also be given to the players supporting the Grineer. A player hacked four conflict nodes, setting those nodes to Corpus victories; as a result, DE removed those nodes from the event victory tally. The Grineer players still managed to achieve victory even after losing four nodes.
*** The Grineer supporters were apparently so determined that they messed up developer plans for the event, forcing them to make changes mid-way through, three times.
* The PS4 [[http://www.youtube.com/watch?v=g-UOTq2nw2k update 11 launch trailer]], where Alad V has cut up and auctioned off an Excalibur, and is about to send an unfortunate Mag to the void... then four Tenno show up to [[BigDamnHeroes have words with him]].
** The best part? There is no GameplayAndStorySegregation. Every single action and ability seen in the trailer can be executed in game. Even Rhino going fisticuffs can be done provided you have one of the gauntlet style weapons (Rhino in the trailer moves ''exactly'' as if he had the Obex gauntlets mounted, although they're not shown in the video).
*** The powers on display work as advertised (eg. Volt's shock can and will take out large groups of [=MOAs=]).
** The one unpredictable in-game bit is still incredibly awesome. Rhino pounces on the downed Zanuka, then starts beating on it, then grabs it and ''rips it in half''.
*** Part of that is actually able to be replicated in-game. Granted, you can't rip enemies in half, but the whole "stand over a fallen enemy and beat them savagely with your fists" thing? Totally doable in-game. And yes, this sometimes results in the enemy getting split in half. ''Lengthwise.''
* The faction conflict missions where you can pick sides. Not only are you mowing down the opposing force, leading the charge of the allied soldiers - you're also moving between two warring ships in some missions. When working for Corpus you are propelled/teleported right into a Grineer frigate. Grineer however aren't as subtle and just ram their ships into the Corpus ones to make tunnels. Seeing the grand scope of two groups fighting against each other really gives you idea of the conflict.
* One of the moves of the new WolverineClaws style Venka blades involves headbutting your enemy to death.
* The death of the original Mirage. Alone vs a Sentient army, she runs out of energy, has a ship dropped on her, loses her shields and her weapons. Does she give up? No, she starts tearing them apart barehanded while laughing like a loon. And she is a caster.
* Digital Extreme pull out all the stops when it comes to updates.
** Melee 2.0, while late in arrival, made rather dull melee combat much more awesome.
** Revamped entire main menu UI.
** The revamped Tutorial in its entirety. Instead of having to be saved by other Tenno, you manage to escape Vor's outpost ''singlehandedly'', cutting through scores of Grineer and even having a short standoff with Vor himself. All while intense music plays in the background.
*** Vor himself has TookALevelInBadass. In the original prologue, he doesn't appear until the end of the segment, but this time, he personally leads the Grineer in awakening the Tenno, and successfully subdues you by ''dropkicking'' you to your knees and injecting you with a MindControl parasite. Only the Lotus' timely intervention saves you.
** [[https://www.youtube.com/watch?v=8eNJ0YpCvmE Archwing]] which puts the Tenno against ''freaking warship'' in the depths of empty space.
*** Unfortunately, the WaveMotionGun lasers that are "designed to destroy captial warships" are difficult to dodge and will OneHitKill all but the toughest of warframes. Which can either force you to burn through several revives to keep going, or feel really good about yourself as you dodge-roll away from the lasers, missing them by a hair. Points also awarded to the gunner who actually manages to ''hit'' the comparably tiny player with said lasers.
* Red Veil, a resistance group composed of normal humans, still manages to came out as the most violent out of the six syndicates.
** The Grineer seems to exercise special caution against them. Way to go.
* One of the Archwing tilesets is a ruined, burning Corpus ship. You can zip through its narrow corridors in high velocities, a la ''Franchise/StarWars'' trench runs.
* The updated J3-Golem is, quite frankly, ''awesome''. What was once a simple reskin of a regular Infested enemy has become an absolutely gigantic multi-layered boss fight against the hugest opponent that the Tenno have had to face yet, in a fight that has you start out in a regular ship, hop into your Archwing to fight the Infested monstrosity, and finally ''go inside of it'' to rip it apart from the inside. DE has outdone themselves with this rework.
