Arms of God Co-op Multiplayer Guide — How to Play With Friends [2026]
Co-op Overview
Arms of God supports 2-player online co-op. Both players share the same screen (no split-screen) and progress through the game together. Boss HP scales by +60%, but the tactical advantage of two coordinated players more than compensates.
How to Start a Co-op Session
1. Main Menu → Multiplayer → Host Game
2. Set privacy: Friends Only or Invite Only
3. Share the session code (6 digits) with your co-op partner
4. Partner: Main Menu → Multiplayer → Join Game → enter code
Both players need to own the game. Cross-play is supported between Steam and Epic Games Store.
Co-op Scaling
| Stat | Solo | Co-op |
|---|---|---|
| Boss HP | 100% | 160% |
| Enemy density | 100% | 150% |
| Gold drops | 100% | 75% per player (150% total) |
| XP | 100% | 90% per player |
| Blessing drops | 100% | 100% per player |
Gold and XP are slightly less efficient per player in co-op, but faster clear times mean you complete runs faster — roughly equal efficiency overall.
Best Duo Compositions
S-Tier: Tank + DPS
- Paladin (tank, aggro control) + Assassin (back-attack DPS)
- Paladin holds boss aggro while Assassin sits behind the boss with permanent back-attack bonus
- Synergy: Paladin's Divine Form (team shield) + Assassin's Phantom Requiem (uninterrupted DPS window)
A-Tier: Double Elemental
- Mage (fire) + Mage (ice)
- One applies burn, the other freezes. Permafrost +30% damage + Kindling extended burns = permanent damage multiplier
- Best room clear speed in co-op. Bosses take longer but trash rooms are instant
A-Tier: Support + Carry
- Priest (healing, buffs) + Devastator (AOE damage)
- Priest keeps Devastator alive through aggressive positioning. Devastator's wide AOE clears rooms while Priest provides sustain
Co-op-Specific Tips
- Coordinate Divine Forms: Stacking Divine Forms (activating both within 2 seconds) grants a 3-second window of doubled damage output. Use this window on boss phase transitions.
- Share blessing drops: If a blessing is perfect for your partner's build, let them take it. A stronger partner is more valuable than a suboptimal blessing on your build.
- Revive mechanic: Downed players can be revived by standing near them for 3 seconds. Both players take 30% reduced damage during revive animation. Always revive during boss downtime windows.
