Challenge Reward

Challenge Rewards are rewards given for completing randomly generated challenges given to Tenno when they begin a mission. The challenge is displayed briefly above the weapon information in the lower-right corner of the screen at the beginning of a mission. When completed, 500 Affinity is applied to the Warframe.

List of Challenges
Here is a list of challenges:
 * Hacker: Hack 1 console.
 * Hacking data terminals does not count towards this challenge. Only terminals that result in a lock out of key areas count.
 * An easy way to get this is to break reinforced glass then hack a terminal.
 * A Cipher can be used to make this even easier.
 * Head Hunter: Get 10 headshots.
 * An enemy must be killed by the headshot for it to count towards this challenge.
 * Killer: Get 30 kills.
 * Looter: Collect 4 energy orbs.
 * Having no abilities means energy cannot be collected, making this challenge impossible.
 * Actually, you can still collect energy until you reach your cap. Dying and being revived resets your energy to the starting value (100). Combining these or having a high energy cap allow you to complete this challenge without ability use.
 * Pistol Master: Get 20 kills with your pistol.
 * Power: Use your first ability 5 times.
 * There appears to be a hidden level requirement in regards to this challenge. This may be a bug in relation to before update 7 when mods were introduced. If a player's level is too low to get their first ability (in the old system), then it may not count towards this challenge. This is purely speculation.
 * Rifleman: Get 30 rifle kills.
 * Kills from any type of primary weapon are counted towards this challenge.
 * Speed Kill: Get 3 kills in 10 seconds.
 * Timer will start upon the first kill. Any kills within 10 seconds go toward the challenge. If a third kill is not achieved before the 10 seconds are up, the counter will reset to 0. For example: Get 1 kill; timer starts; get another kill (2/3); 10 seconds expires from time of first kill and the counter has reset to 0 kills; get another kill and it will be at 1/3. The second kill from the first timer will not count towards the second timer.
 * Stealth: Get 10 kills on unalerted enemies.
 * Unalerted Corpus camera kills are counted toward this challenge. Once a camera has detected a Tenno, it will thereafter be considered "alerted," even if it returns to its normal "scanning" state.
 * Style Kill: Get 5 kills while sliding.
 * This includes any kills attained with weapons, Warframe abilities or your sentinel
 * Swordsman: Get 10 melee kills.
 * Treasure Hunter: Find 1 artifact module.
 * Uber: Use your [4th] warframe ability once.
 * There appears to be a hidden level requirement in regards to this challenge. This may be a bug in relation to before update 7 when mods were introduced. If a player's level is too low to get their fourth ability (in the old system), then it may not count towards this challenge. This is purely speculation.
