Now let's move onto the weapons, currently there are almost 300 weapons including the variants between primary, secondary and melee weapons, you will never get bored of the ever growing collection of weapons. Warframe has some of the most unique combat, there is really no equal. Truly the most unique feature though is the melee combat. Back in “vanilla” Warframe the melee weapons were just something you would have on your back and you would hit the attack button make a quick slash then put it back. Now each type of melee weapon has their own stances with multiple to choose from and what they do is give your melee weapons combos or move sets in other words, and if that sounds cheesy to you then you have yet to try it. Using your favorite melee weapon with a stance you like best and running around doing your combos in spectacular fashion is some of the most fun one can have in this game. Just writing about this cannot do the melee system justice, it's more than worth a try just for that.
The second chunk of content that desires your attention are the quests that have been added into the game over the last few years. New warframes are primarily acquired through quests which as you play, you find out about the lore of the warframe in question. This feature removes the need to farm for the parts of the frame like the old days. The other kind of quests are story quests. Besides the lore and speculation, no story existed a few years ago, now there are two story quests which take you on a journey to learn a lot about your warframes which are shrouded in mystery. They are extremely engaging and will hook you on warframe. Without giving to much away, the story quests answer all the right questions while still creating even more more mystery. It generates so much new lore that this game will keep you knee deep in the trenches for a very long time.
Tilesets and Missions
Warframe has many missions spread out across the universe, some not even in the normal plain of existence your usually in, and warframe is generally a game that requires farming missions every now and again for resources in order to build things, that being said it would be extremely boring if you just played the exact same mission over and over and the developers are fully aware of that so they have slightly different tile sets for the same mission. Tile sets are different wallpaper on the same mission essentially. It can be slightly different or uncomparable from what it used to be. Also every single mission in the game will have you start in a random area, so to get to the same objective in the same spot you will start in a different spot every time and get there a different way going through a whole different set of rooms. That is a feature many will take for granted but one that makes a large difference.
