AfterFifteen - Nuclear Apocalypse Survival
AfterFifteen is a hardcore survival mod that adds a personalized radiation system for each player. Every player has their own timer, their own radiation level, and their own consequences.
🌍 The Cycle
The mod works in a three-phase cycle for each player independently:
⏰ Phase 1: PROTECTION (Default: 15 minutes)
After first join, you have 15 minutes to prepare. Gather resources, build a shelter, or dig deep. The countdown has begun...
☢️ Phase 2: RADIATION (Dimension dependent)
- Overworld: 7 days
- Nether: 21 days
- End: 28 days
During this phase, the surface is contaminated! You'll accumulate radiation based on your height:
- Above 64 blocks: ×2.0 radiation (MOST DANGEROUS)
- 51-64 blocks: ×1.5 radiation (DANGEROUS)
- Below 50 blocks: SAFE ZONE (no radiation)
⏳ Phase 3: IDLE
After radiation ends, you enter an idle phase. No timers, no radiation - just hallucinations from what you've experienced...
🩻 Radiation Sickness (10 stages)
As your radiation level increases, you'll experience worsening effects:
| Stage | Radiation | Effects |
|---|---|---|
| 1 | 5-14% | Nausea, Weakness I |
| 2 | 15-24% | Weakness II, Hunger I |
| 3 | 25-34% | Slowness I, Hunger II |
| 4 | 35-44% | Mining Fatigue I, Slowness II |
| 5 | 45-54% | Blindness, 1.0❤️ damage |
| 6 | 55-64% | Poison I, 1.5❤️ damage |
| 7 | 65-74% | Unluck, 2.0❤️ damage |
| 8 | 75-84% | Wither I, 2.5❤️ damage |
| 9 | 85-94% | Darkness, 3.0❤️ damage |
| 10 | 95%+ | DEATH APPROACHING! 4.0❤️ damage |
👻 Hallucinations
When radiation drops to zero, you'll experience 2 hours of hallucinations:
- Fake mob sounds (zombies, skeletons, creepers)
- Herobrine sightings
- Explosion sounds
- Item pickup/drop sounds
- Chat messages from "unknown players"
- Random slot swapping
- And much more...
