The Blood Strike MENA Seven Deadly Sins crossover runs April 3 to May 3, 2026 — and F2P players can claim every core reward without spending a single diamond. Four free weapon skins (QBZ95, Kar98k, AK47, M700), three Playpals, three avatars, a frame, and a title are all unlockable through login streaks, mode participation, friend invites, and gallery tasks. Premium gacha skins exist but are entirely optional.
What Is the 7 Deadly Sins Event? (2026 Overview)
This is a full anime crossover — not a reskinned seasonal event. Blood Strike partnered with The Seven Deadly Sins franchise to bring character-themed cosmetics, a dedicated limited mode, and a multi-week reward calendar built around consistent play.
The centerpiece is Sin Mark Duel, a limited mode where you interact with Crest Stone Pillars scattered across the map. Each pillar grants Crest Abilities — combat buffs tied to the Seven Deadly Sins lore. You're not just grinding missions; the mode plays mechanically differently from standard Blood Strike, with anime-flavored power-ups that actually affect match outcomes.
Cosmetics pull directly from the anime roster. Elizabeth, Hawk, Meliodas, and the Sacred Axe Rhitta all appear as named weapon skins or Playpals. One of the more lore-faithful crossovers Blood Strike has run.
Event Schedule
No MENA-specific date deviations have been confirmed — the schedule above applies to MENA servers.
Complete Reward List: Every Free Skin & Item
Everything below is obtainable without diamonds. The unlock method is what varies.
Premium gacha-only skins (Featured Treasure draws, gold or diamonds required):
M4A1 – Demon
Galil – Elizabeth
LUCIAN – Meliodas (Demon)
EMMA – Elizabeth (Goddess)
Those four are the only items behind a paywall. Everything else in the table is genuinely free.
One Clarification Worth Making
Some guides reference "sin tokens" or individual sin-path unlock tracks — Wrath tokens, Greed currency, that kind of thing. This is not how the event works. Official patch notes confirm no event currency system exists. Rewards unlock through login days, mode participation, friend invites, and task completion. Nothing to farm, nothing to exchange. The event is more accessible than it sounds.
The "Wrath of the Gods" title is the closest direct sin reference in the free pool. Confirmed skin naming follows character names from the anime (Elizabeth, Meliodas, Hawk, Rhitta) — not individual sin labels.
F2P vs Spender: What Do You Actually Get?
Four weapon skins across four different weapon classes from a single event is genuinely unusual. Most Blood Strike limited events offer one or two. The F2P haul here is strong.
Will these skins return? Official patch notes confirm all collab items are removed after May 3, 2026. Based on how Blood Strike has handled prior anime crossovers, returning collab events are rare and typically repackaged differently. Treat the Kar98k Double Bow Harlit and AK47 Sacred Axe Rhitta as permanently exclusive to this window.
How to Unlock Everything: Step-by-Step
Four distinct mechanics drive the reward tracks. Here's how to approach each one.
1. Login Streak → Kar98k Double Bow Harlit + Avatars
Log in daily from April 3. You don't need consecutive days, but missing days delays the unlock. This is the most passive reward — set a daily reminder and don't overthink it. Players who miss the first week often fall short of the login threshold before May 3.
2. Mode Participation → QBZ95 + Playpal Oslo
Play matches in Sin Mark Duel. Official notes confirm participation drives progress — losses count. Play consistently throughout the event rather than cramming at the end.
Don't just treat Sin Mark Duel as a reward vehicle. The Crest Stone Pillars grant Crest Abilities that can swing matches. Learning which pillars to contest early gives you a real competitive edge — the mode rewards aggressive early positioning more than standard deathmatch play styles.
3. Friend Invites → AK47 + M700
Two separate windows, two different mechanics:
AK47 – Sacred Axe Rhitta: Invite friends, April 6–19
M700 – Elizabeth: Invite friends to slash price, April 17–May 3
The AK47 window is the tightest deadline in the entire event — it closes April 19. Activate this track on April 6 if you have active friends or know anyone who hasn't downloaded the game yet. Important: the invite mechanic requires active participation from the invited friend, not just sending a link. A friend who downloads but never logs in likely won't count.
4. Gallery/Puzzle Tasks → Playpal Guardian + Title Wrath of the Gods
Window runs April 13–29. Check the event tab specifically on April 13 — don't assume these tasks were available from day one. They typically have daily or weekly completion caps, so spreading them out is more efficient than attempting everything in one session.
5. Team Activity → Playpal Hawk + Avatar Elizabeth
Opens April 20 — the latest start of any reward track. Squad up with friends or use in-game team matching. Coordinating with a consistent squad rather than random teammates significantly speeds up task completion, especially if objectives require specific in-match actions.
Late Joiner Catch-Up
The M700 Elizabeth skin has the most forgiving window (April 17–May 3) and is the best target for late joiners who still have active friends to invite.
Is It Worth Spending Diamonds?
The free track is exceptional value — complete it first, no question. The gacha skins are a separate calculation.
Without confirmed pity system details for this specific event, budgeting for gacha is genuinely hard to predict. Gacha rates in Blood Strike events are variable — go in with a fixed spend limit rather than chasing a specific skin.
If you're planning to top up before the event closes, getting the best rate on your diamonds matters. Blood Strike (MENA) cheap recharge on BitTopup offers competitive pricing with fast delivery — worth checking before committing, especially if you're targeting multiple Featured Treasure pulls before May 3.
FAQ
Can I still get free skins if I missed the first week? Most tracks are still catchable in week two. The Kar98k login skin may be out of reach if you join very late. Hard miss: the AK47 Sacred Axe Rhitta invite window closes April 19 — after that date, it's gone.
Do event items carry over after May 3? No. Official patch notes confirm all collab cosmetics are removed after May 3, 2026. No grace period, no carry-over.
Is there a sin token or event currency to manage? No — this is a common misconception. Official sources confirm no event currency system. Rewards unlock through login days, mode participation, friend invites, and task completion.
Which skin has the highest community display value? Among gacha skins, EMMA Elizabeth (Goddess) and LUCIAN Meliodas (Demon) are likely the most visually distinctive. Among free skins, the Kar98k Double Bow Harlit stands out — strong anime-faithful design on a sniper that sees consistent use.
Will the Seven Deadly Sins skins return? No confirmed return has been announced. Official patch notes label all collab items as limited-time. Don't sit on the fence about grinding the free tracks — just do it.
Is Sin Mark Duel available after the event ends? Sin Mark Duel is tied to the April 3–May 3 window. No official announcement of a permanent mode addition has been made.
