Bonuses¶

Bonuses drop from killed creatures. Walk within 26 units of one to collect it. There are 14 types: timed effects, one-shot bursts and instant rewards.

Durations below are base values. Bonus Economist makes every timed bonus last 1.5× as long. Picking up a timed bonus that is already running adds its full duration to the time left. While Reflex Boost runs, every bonus timer counts down in slow motion too.

1. Points¶

Adds 500 XP, or 1000 XP with a 3-in-8 chance. Double Experience doesn't double it.

2. Energizer¶

Duration: 8 seconds. The rarest bonus: 1 in 8,576 drop rolls.

Creatures under 500 max HP run away from you. Creatures under 380 max HP that come within 20 units are eaten: they die instantly, pay their XP twice (three times with Double Experience) and drop no bonus. The extra payment ignores Bloody Mess, so with it an eaten creature pays 2.3× (3.6× with Double Experience). No creature can hurt you by touch, but ranged shots still hit.

3. Weapon¶

Replaces the gun in your hands with a random unlocked weapon, fully loaded and ready to fire. With Alternate Weapon the other slot is left alone. The gun is chosen when the bonus drops. A gun you've been handed before, in any run, gets rerolled half the time, so the pick favours guns you've never had.

A Weapon from the normal drop roll that lands within 56 units of a player turns into a 100-point bonus instead. Weapon drops stop entirely with My Favourite Weapon.

4. Weapon Power Up¶

Duration: 10 seconds.

You fire 50% faster and reloads take 60% as long (42% with Fastloader). Pickup refills your clip and cancels any reload. The timer is shared: in co-op it powers up both players, but only the one who picks it up gets the refill.

5. Nuke¶

Instant. A blast hits every creature within 256 units for (256 − distance) × 5 damage: 1,280 at the centre, nothing at the edge. It also throws 4–7 pistol bullets and 2 gauss shots in random directions.

Blast kills drop no bonuses. Kills by the stray bullets can.

6. Double Experience¶

Duration: 6 seconds.

Every kill pays double XP.

7. Shock Chain¶

Instant. Fires an Ion Rifle shot at the nearest creature. Each hit jumps to the nearest creature at least 100 units away, up to 32 links. There is no maximum jump distance, so a chain can cross the whole arena.

No second Shock Chain drops while one is still jumping. Chain shots don't count toward your shots fired.

8. Fireblast¶

Instant. Fires 16 Plasma Rifle shots in a ring, 22.5° apart, from the pickup point.

The shots don't count toward your shots fired, and Fire Bullets doesn't convert them. Their kills drop bonuses as usual.

9. Reflex Boost¶

Duration: 3 seconds of game time, about 8.4 real seconds (13.4 with Bonus Economist).

The world runs at 30% speed, ramping back to full speed over the last second. You move at 60% speed, twice as quick as everything else, but your gun slows down with the world. Shots cost no ammo while it runs. Pickup refills every player's clip and cancels their reloads.

10. Shield¶

Duration: 7 seconds. In co-op, each player has their own.

Blocks all damage: contact, enemy shots, and self-damage from perks like Ammunition Within. Hits don't shorten it.

11. Freeze¶

Duration: 5 seconds.

Creatures stop moving and attacking. Anything killed while frozen shatters and leaves no corpse, and pickup shatters any corpses already lying around. No second Freeze drops while one is running.

12. MediKit¶

Instant. Restores 10 HP, up to 100. Never drops while Death Clock is active.

A dead player's body still collects bonuses. A MediKit brings them back if the killing blow left them above −10 HP and it lands in reach before the run ends; see Death.

13. Speed¶

Duration: 8 seconds. In co-op, each player has their own.

You move 50% faster.

14. Fire Bullets¶

Duration: 5 seconds. In co-op, each player has their own.

Every shot becomes fire bullets, one per pellet of your current gun, and costs no ammo. Pickup refills your clip and cancels any reload.

For how Fire Bullets changed between versions, see Fire Bullets 1.9.8 vs 1.9.93.

Drop chances¶

Each kill rolls 1-in-9 (11.1%) for a drop. Bonus Magnet gives a failed roll a second 1-in-10 chance (20% in all).

While you hold the Pistol, 3 kills in 4 try to drop a Weapon instead (never the Pistol). The try is cancelled if a Weapon is already on the ground, and Bonus Magnet doesn't apply to it. The other kills roll 1-in-9, then an extra 1-in-5 (28.9%), then Bonus Magnet (36%).

A drop is cancelled if:

• the kill is within 32 units of the arena edge;
• another bonus lies within 32 units;
• 16 bonuses are already out;
• a bonus of the same type (other than Points) is already on the ground;
• it's a Weapon you or a co-op partner already carries, in either slot.

The type comes from this table:

A suppressed type is rerolled, up to 100 times, then the drop becomes Points.

Suppression rules¶

• Shock Chain: while a chain is still jumping.
• Freeze: while Freeze is running.
• Shield: while any player has a shield.
• Weapon: with My Favourite Weapon, or while a Fire Bullets bonus lies on the ground.
• MediKit: with Death Clock.
• Nuke: in quests 2.10, 4.10 and 5.10, and in 3.10 on hardcore.
• Freeze: in quest 4.10, and in 2.10 on hardcore.

On the ground¶

Unpicked bonuses vanish after 10 seconds, except in the tutorial.

By mode¶

• Survival and Quests: all bonuses drop, minus the quest rules above.
• Rush and Typ-o-Shooter: no bonuses.
• Tutorial: no random drops. The script places three Points bonuses, then Speed, Weapon (Submachine Gun), Double Experience, Nuke and Reflex Boost.
