All 4 weapon skins in Blood Strike MENA's Seven Deadly Sins event are completely free — no diamonds required. Official patch notes and community testing both confirm it. The event runs April 3 to May 3, 2026, MENA server only, and each skin sits behind its own independent track with its own deadline. Miss a window and that reward is gone permanently. No grace period.
What Is the Seven Deadly Sins Event?
Five parallel reward tracks, each with its own task type, time window, and reward set. No shared event currency. No point pool. You complete a track's tasks within its window, or you don't. That structure cuts the grind — but it also means one missed deadline is unrecoverable.
All Rewards at a Glance
The 4 weapon skins are the headline rewards. Playpals, avatars, frames, and the title are bonus cosmetic value on top.
Is This Actually F2P?
Yes, unambiguously. Official patch notes explicitly separate these free track rewards from the paid gacha pool (which includes skins like the M4A1-Demon). Community testing across the MENA server confirms zero diamonds needed for all 4 weapon skins. Realistic daily time investment: 15–20 minutes over 30 days.
The 4 Free Skins: Requirements
QBZ95 – Coffin of Eternal Darkness
Unlocked via the Sin Mark Duel track, which runs the full event duration. Play 2–3 matches daily in this limited-time mode. Losses count — wins aren't required. Most forgiving track in the event. Even if you start a few days late, this skin is recoverable.
Kar98k – Double Bow Harlit
Pure login accumulation. Log in daily from April 3 and the Kar98k unlocks automatically once you hit the required threshold. Missing individual days delays progress but doesn't break the track — you can recover before May 3 as long as you don't miss too many consecutive days. The Hawk avatar and one crossover frame also come through this track.
AK47 – Sacred Axe Rhitta
This is the skin most players miss. The invite window opens April 6 and hard closes April 19 — 13 days, no extensions. Invited friends must actively participate in the event for invites to count. Inactive accounts don't register. Prepare your active friend list before April 6. Don't wait until April 10 thinking you have time.
M700 – Elizabeth
The second invite-track skin, running April 17 to May 3. Critical detail: April 17–19 is an overlap window where both the AK47 and M700 invite tracks are simultaneously active. Invites sent during those three days count toward both tracks at once. Don't waste that overlap by waiting until April 20 to start the M700 track.
Step-by-Step Unlock Guide
Step 1 — Find the Event
From the Blood Strike MENA main lobby, open the event menu. The Seven Deadly Sins event has its own dedicated section — all five tracks, progress indicators, and claim buttons live there. Check it daily. New track windows open on specific dates (gallery opens April 13, team-up opens April 20), and you won't get a push notification for every one.
Step 2 — Understand the Track System
Stop looking for event points. There aren't any. Each track is a direct task-to-reward pipeline: complete the tasks within the window, then manually claim the reward in the event menu. Players who approach this like a point-farming event waste time on the wrong activities.
Step 3 — Sin Mark Duel (QBZ95 Track)
This limited-time mode features Crest Stone Pillars — map objects that grant temporary Crest Abilities buffs. Rush a pillar within the first 60 seconds of each match; the early buff advantage is significant. For the QBZ95 unlock, 2–3 matches per day is enough and wins don't matter. But understanding the pillar mechanic makes those daily sessions more competitive if you care about performance beyond the checkbox.
Step 4 — Friend Invite Tracks (AK47 + M700)
Send invites starting April 6 for the AK47 track. During the April 17–19 overlap, prioritize sending any remaining invites — they work double duty for both skins simultaneously. Invited friends must actively engage with the event. Inviting inactive accounts won't count toward your progress.
Step 5 — Gallery Tasks (April 13–29): Don't Delay
The gallery track opens April 13 and closes April 29. This is a multi-step chain — earlier steps gate later ones. Starting April 14 or 15 is fine. Starting April 22 almost certainly isn't enough time. The Second Form Guardian Playpal, Meliodas avatar, and Wrath of the Gods title all depend on this track. Open it the day it launches.
Step 6 — Claim Manually Before May 3
Rewards don't auto-deliver. After hitting a track's completion threshold, you must go into the event menu and manually redeem each reward. Unclaimed rewards are permanently lost after May 3 — official confirmation, no exceptions. Check the event menu every session, not just when you think you've finished something.
Daily Checklist
April 3–7 (Foundation Phase)
Log in and claim login reward
Play 2–3 Sin Mark Duel matches (rush Crest Pillars early)
Send friend invites as soon as the window opens April 6
Check event menu for newly claimable rewards
April 8–19 (Critical Invite Window)
Continue daily login + Sin Mark Duel
Actively push friend invites — only window for the AK47
April 13: Gallery track opens — start immediately
April 17–19: Overlap window — invites count for both AK47 and M700 simultaneously
April 20–May 3 (Completion Phase)
Team-up tasks open April 20 — add to daily routine
Continue gallery chain through April 29 deadline
Continue login accumulation and Sin Mark Duel
Final 48 hours: audit every track, claim everything unclaimed
Total daily time: 15–20 minutes. Sin Mark Duel matches are the longest block; everything else takes minutes.
The AK47 Mistake Most Players Make
Most guides list the AK47 as a simple "invite friends" task and move on. What they skip: the April 19 deadline is a hard cutoff with zero exceptions, and the invite window only opens April 6. That's 13 days. If your friend list is full of inactive accounts — or you're not actively playing during that window — you miss this skin permanently.
The fix requires advance action: before April 6, identify 3–5 friends who are actively playing Blood Strike MENA and will engage with the event. Confirm they're participating. Send invites the moment the window opens.
Players starting after April 19 should accept the AK47 is gone and redirect energy to the remaining three skins, all of which are still achievable.
Late Starter Catch-Up Plan
Starting late? Prioritize in this order: QBZ95 first (most forgiving, losses count, runs full event), then Kar98k (start login accumulation immediately), then M700 (invite track open until May 3), then assess gallery feasibility based on your actual start date.

FAQ
Do the free skins expire after the event? No. Once claimed before May 3, they're permanently yours. The expiry only applies to unclaimed rewards sitting in the event menu — those disappear after May 3 with no recovery.
Is there an event currency to track? No, and this trips up a lot of players. Five independent tracks, each with its own task completion requirements. Don't look for a point meter.
Can I still get all 4 skins if I missed the first week? Starting between April 6–13, yes — all 4 are achievable with consistent daily play. After April 19, the AK47 is permanently gone. After April 29, you're realistically looking at QBZ95 and Kar98k only.
Where do I claim the skins in the UI? Inside the event menu from the main lobby. Each track has its own section with a claim button that activates once you hit the completion threshold. If the button isn't there, you haven't finished the track requirements yet.
Do invited friends need to do anything specific? Yes — community testing confirms invited friends must actively participate in the event for the invite to register. Inviting inactive accounts won't count. This is why preparing your active friend list before April 6 actually matters.
Will these skins return after the event? Official patch notes don't address re-release schedules. Based on how Blood Strike MENA has handled previous collab events, community consensus treats these as limited-time exclusives — but that's community inference, not confirmed developer policy.
Final Verdict
Four weapon skins, three playpals, three avatars, two frames, and a title — all free, all achievable in 15–20 minutes daily. The Seven Deadly Sins event is one of the more generous F2P structures Blood Strike MENA has run, specifically because it doesn't funnel everything through a single grindable currency requiring hours of daily farming.
The trade-off is strict date windows. The event rewards attentiveness more than raw playtime.
Casual F2P players: Focus on QBZ95 (Sin Mark Duel, very forgiving) and Kar98k (just log in). Both require minimal coordination and flexible timing.
Dedicated F2P players: All 4 skins are realistic with 30 days of light daily commitment. The only real effort is friend invite coordination for the AK47 and M700 — everything else is low-friction.

Set a daily alarm. Check the event menu every session. Prepare your friend list before April 6. Start the gallery the moment it opens April 13. Do those four things and all 4 free skins are yours.
