Similar to many On-Hit effect weapons, shooting an invulnerable enemy will still fill the Boost meter, and shooting disguised Spies will not grant boost. Ground jumps will not lower the Boost meter. If the Scout takes damage or jumps mid air while using the Baby Face's Blaster, the Boost meter is reduced, by 4% for each damage point (25 damage to bring a full meter down to 0) and 75% for each air jump, causing the Scout to lose momentum.

The Boost meter fills completely when the Scout deals 100 points of damage using any weapon. As the Boost meter charges, the Scout's speed will increase linearly from 360 units/second to 520 units/second (173% movement speed). However, for every point of damage dealt with any weapon, the Scout builds up a "Boost" meter (though the minimum Boost gained from any damage dealt is 5%). The Baby Face's Blaster only has a clip of four, instead of six compared with the Scattergun, and will slow the Scout down from 400 units/second (133% movement speed), to 360 units/second (120% movement speed). It is a short, slightly modified lever-action shotgun with a wooden handle and single barrel. The Baby Face's Blaster is a community-created primary weapon for the Scout.
