The SMART computer used on the Spitfire is tasked with calculating atmospheric conditions between the weapon and the target, while also generating a strange particle field. The field causes bullets to lose mass for a short period of time, reducing weapon recoil and increasing accuracy.
The V.L.I.-35 is an automatic rifle comparable to weapons such as the Stacker and the Grinder; sporting high damage, low recoil, an extremely high rate of fire, and maximum armor penetration, as well as a very fast reload time compared to most primary weapons of the Sapper class (though slightly less than that of the Stacker). Like the Stacker, it cannot equip a grip to improve accuracy, and bullet spread becomes noticeable at longer range engagements, making it optimal for close-mid range encounters.
However. the unique mechanic of the weapon causes each successful hit to increases the accuracy of the weapon by 20%, which can be stacked up to 10 times with each stack lasting 20 seconds; potentially allowing it to be accurate and deadly at much longer ranges.
