Experimental Weapon 1

Experimental Weapon 1 (EW1) is a new special weapon introduced in Ace Combat: Assault Horizon.

Ace Combat: Assault Horizon
EW1 is a player-usable version of the Trinity weapon seen in the single-player campaign. Is is the third secondary weapon of the PAK-FA, which in turn is unlocked by finishing the campaign.

Upon impact, the missile produces a massive, earth-shaking explosion. Like the Trinity warheads seen in the campaign, the impact makes a visible shockwave. Flying too close to the explosion will cause one to be pushed around by the shockwave, although no actual damage will be suffered. Unlike other special weapons of its kind, it is capable of affecting friendlies. A total of three EW1s can be carried at any time; however, the number can be increased to four through the use of skills.

Multiplayer
In any competitive multiplayer mode, an Experimental Weapon 1 may be acquired if a player achieves a killstreak of eight. Once the condition has been fulfilled, the player's callsign will flash on the left-hand side progression window box with the indication that the player has obtained the right to use Trinity, and will be given the choice of respawning in a PAK-FA armed with the weapon. Due to the fast-paced nature of multiplayer modes and the small text that the information box uses, it's helpful to keep track of one's own callsign as well as the amount of kills attributed to the player, as it is easy to overlook when one obtains the weapon. Using the "Easy Trinity" skill will allow one to acquire the weapon with a single kill, though this bonus lasts only for a single match.

Only one Trinity-equipped PAK-FA can be on the field at any time. In Capital Conquest, it is extremely useful for clearing the myriads of anti-air weapons littered around key objectives like HQs, Radar Stations and the like. Once released, even if by mistake, it is then lost and must be reacquired with another killstreak. In addition, if the player is shot down before the EW1 is used, it is lost and must be reacquired.

Upon fielding an EW1-equipped PAK-FA, both team's objectives will change to "Destroy/Protect the EW1 Carrier!". Regardless, the previous objective will remain, and it is suggested, but not necessary to acknowledge the aforementioned player.
