Was Viper in VALORANT at launch?
No, Viper was added after release — only 5 of the current agents shipped with the game at launch.
Is Viper free to play?
Viper has to be unlocked, like every agent beyond the starting few. You do that with Kingdom Credits earned by playing, or with VALORANT Points if you would rather not wait. Unlocking is permanent and no agent is ever sold as a stronger option — the roster is balanced, not tiered by price.
Which agents are Controllers?
There are 7 in the Controller role: Viper, Miks, Harbor, Astra, Brimstone, Clove, Omen. Roles are the game's own grouping, not a community one, and they describe the job an agent does for the team rather than how strong they are.
Viper in professional play
How often professional teams actually pick Viper, measured across 1,820 tournament games played between 2026-05-22 and 2026-08-20. This is professional VALORANT, not ranked — the two behave differently, and a pick rate at this level says more about map strategy than about what wins games in a solo queue.

Where Viper gets picked
| Map | Pick rate | Win rate | Times picked |
|---|---|---|---|
| Split | 17.5% | 50.8% | 472 |
| Breeze | 15.8% | 50.3% | 394 |
| Lotus | 10.6% | 55.4% | 334 |
| Summit | 6% | 38.6% | 44 |
| Haven | 2.5% | 48.1% | 79 |
Pick rate is the share of the ten player slots in a game that this agent filled. Win rate hovers near 50% for almost every agent because professional matches are between evenly matched teams — a figure far from 50% usually means a small sample rather than a strong agent. Maps with too few games to be meaningful are left out entirely rather than shown with a warning.
What Viper's abilities cost

Where Viper sits in the roster
Viper was added after launch. Only 5 of the current roster shipped with the game, and the agents added since tend to carry more conditional or setup-heavy abilities than the originals.
During development Viper went by the internal codename Pandemic, which is the name that still appears in the game files.
There are 30 playable agents in total, 7 of them in the Controller role.
More agents in the Controller role
The other 6 agents who fill the Controller role. If you like how Viper plays, these are the closest thing to a lateral move — same job on the team, different tools.
How Viper’s abilities interact
Interactions involving Viper, from either side — what their abilities do to other agents’ utility, and what other agents can do to theirs.
Viper Snake Bite damages Killjoy Alarmbot
Acid damages deployables in its area. It will finish an Alarmbot, though the more common use is denying the space the bot was watching.
Viper Toxic Screen blocks Sova Recon Bolt
Viper's smoke blocks the dart's line of sight for the same reason it blocks yours. It is one of the few smokes that reliably denies recon rather than merely obscuring it.
