UMP

A better UMP doesn't hit harder. Every star does 19 damage a bullet, 23 on a headshot.

What a star buys is the magazine: 28 rounds at one star, 44 at five.

Every star also takes a little recoil off, so a five-star UMP stays on target longer.

A star changes nothing else: not the reload, not the range or the falloff, not the aim down the sights.

Hold the trigger and it fires 14 rounds a second until the magazine is empty: 2 s of fire at one star, 3.1 s at five.

Reloading is done by hand: the magazine to the well, then the rack. Nothing in the game times a reload.

Against a built wall every hit counts 1.5 times its damage.

It does less damage a bullet than the MP5 and the Silenced MP9, and holds 28 rounds at one star and 44 at five.

A player has 100 health and up to 100 shield. On health alone the UMP downs in 6 body shots or 5 headshots. Through a full shield it takes 11 body shots in about 0.7 s or 9 headshots in about 0.6 s, if everything lands.

Full damage out to 20 m. Past that a bullet does 13 damage and falls to 9 over the next 24 m, then stays at 9 out to the UMP's 160 m range.

A bullet travels at 700 m/s, so a target moving sideways at distance has to be led.

The MP5 does 22 damage a bullet, 13 bullets a second. The Silenced MP9 does 21 damage a bullet, 12 bullets a second. The P90 does 20 damage a bullet, 15 bullets a second. The Uzis do 14 damage a bullet, 13 bullets a second.
