Normal Mode Walkthrough — Undertale Soul OPs 2

This Normal Mode walkthrough covers the full co-op route in Undertale Soul OPs 2 on Roblox — from first Undertale (UT) waves through Omega Chara, Underfell Sans, Outertale Asgore, Multiverse Malfunction Gaster, optional Dio Sans secret, and Endless continuation. Up to five players defend six souls (Defend Souls); this page names every major boss checkpoint so your squad syncs ults and shop buys. Pair it with Getting Started for economy basics and Controls for keybinds.

Run setup and early UT waves

Host selects Normal in lobby. Recommended comp: two Attack, one Defense, one Support, one flex — validate on Team Comp Checker. Starters like Undyne (Tier List) simplify first clears.

UT wave segment introduces trash paths toward souls. Practice perfect waves (+25 coins, Economy) while enemies are slow:

• Inner ring player holds E shields if available
• Outer Attack clears elites before they touch the cluster
• Save R ultimates for the segment boss

Shop after early waves: first Tier step (1,250 coins) beats redundant damage packs if your main is still Tier 1.

How to beat Gaster on the Normal route

Boss — Omega Chara (UT finale)

Omega Chara ends the UT arc with soul spike floors and rush-down phases.

Tell: audio cue before ground spikes under souls Response: inner ring jumps or Support shields; Attack dumps Q during stagger Fail state: two souls cracked going into Underfell — consider extract if pub lobby

Vote skip on repeat intros only after first clear (Controls).

Underfell arc — Underfell Sans

Theme shifts aggressive — shorter wind-ups, blink movement behind players.

Wave tips:

• Keep one player facing backward toward souls
• Do not chase Sans into the soul ring
• Turret on lane you cannot watch during blinks (Economy)

Underfell Sans boss: teleports after bone strings. Burn ultimates when he reappears near outer ring, not souls. Defense class taunts help if your pick has E utility (Playable Characters).

Outertale arc — Outertale Asgore

Outertale adds wider arenas and radial AOEs from Outertale Asgore.

Tell: spear wind-up facing soul cluster Response: whole team sidesteps together — splitting fails Perfect wave note: radial hits often tag multiple souls; prioritize dodge over greed kills

Tier 2–3 expected by here for pub matchmaking comfort (Tier Unlock Planner).

Multiverse Malfunction — Gaster

Final Normal boss Gaster — full mechanics in Beat Gaster:

1. Find real clone among fakes
2. Land 50 hits for stun
3. Throw souls at Universe Core through six movement phases

This walkthrough does not duplicate phase tables — read that guide before queueing if you are shot-caller.

Clearing Gaster unlocks Endless Mode (Endless).

Secret — Dio Sans coffin

After Gaster (or during specific lobby conditions documented in Secrets and the dedicated Dio Sans guide), squads can trigger a hidden Dio Sans coffin encounter. Optional — skip if farming Endless efficiency.

Requires coordinated interact search and burst DPS similar to mini Boss Rush pacing. Rewards badge progress toward unlocks (Unlock Characters).

Endless continuation

Host selects continue for scaling waves. See Endless for farming strategy. Normal walkthrough ends narratively at Gaster; Endless is post-game.

Hard Mode contrast

Hard Mode (Hard Mode) replaces late arcs with Underswap, Fresh, and Nightmare bosses — not covered step-by-step here. Normal walkthrough mastery is prerequisite.

Wave-by-wave shop timing

Squad communication script

Progression after first Normal clear

1. Farm Endless for Tier 5 (Economy)
2. Chase badges (Unlock Characters)

4. Track Updates and Events for route changes

No promo codes accelerate clears (Codes). Avoid Scripts — boss telegraphs are learnable.
