How the Summer Sisters Trainer Works
This trainer attaches to the Summer Sisters process in memory and toggles specific variables — health pool, ammo count, experience multiplier — without modifying game files on disk. No reshades, no DLLs injected into protected modules, no savegame corruption.
How to Install
- Download the archive from the link below.
- Right-click the archive and extract it with 7-Zip or WinRAR (password: flingtrainer).
- Temporarily disable your antivirus or whitelist the extracted folder.
- Launch Summer Sisters and load any save.
- Alt-Tab out of the game, right-click the trainer executable and choose “Run as administrator”.
- Back in-game, press the listed hotkeys (usually F1, F2, F3…) to toggle each option.
- Avoid alt-tabbing repeatedly while cheats are active — some toggles reset on window switch.
How This Trainer Compares
Compared to generic cheat engines, this release ships with pre-built, version-locked hotkeys — no manual pointer hunting, no CE-script imports, no waiting for community tables to catch up. The downside is less flexibility: you cannot add custom options, but the upside is near-zero setup friction and a faster patch cycle after every Kagura Games update.
Pro Tips from the Editor
- Run the trainer after loading into a save, not from the main menu. Some games replay the intro with modified memory and glitch.
- Quick-save in Summer Sisters just before toggling any XP or economy cheat — that way a rogue multiplier never snowballs your progression.
- Pair One-Hit Kill with Stealth Mode in open-world maps to clear camps without spawning reinforcements.
- If Windows Defender deletes the exe on download, add the folder to exclusions before extracting the archive.

Safe to Use — Antivirus False Positive Notice
This trainer uses memory-editing technology to modify game values in real time. Some antivirus programs may flag it as suspicious — this is a known false positive common to all memory-editing software, not an indication of malware.
Verify the file yourself: Upload it to VirusTotal.com to scan with 70+ antivirus engines before running.
How to Install the Summer Sisters Trainer
- Download the trainer archive from this page (button above).
- Extract with WinRAR or 7-Zip — password if any is shown beside the download.
- Disable real-time antivirus only if a false positive blocks extraction. Trainers modify game memory; many AVs flag this as a generic heuristic. The included VirusTotal scan is your sanity check.
- Launch the game first, reach the main menu, then start the trainer as Administrator.
- Use the listed function keys (F1–F12) to toggle each cheat — health, stamina, money, ammo, instant skill cooldown and so on.
Compatibility & Anti-Cheat
Summer Sisters trainer targets the single-player and offline modes on the exact game build noted at the top of this page. It is not designed for online or multiplayer play and should never be used with Easy Anti-Cheat, BattlEye, FairFight, or VAC-protected lobbies — running a trainer there can result in a permanent ban from the game's matchmaking servers.
Troubleshooting
If the trainer hotkeys don't activate: confirm the game version above matches your installed copy (Steam → game properties → Updates), install the latest Visual C++ Redistributables, and verify your antivirus hasn't quarantined the executable. After a game update, check this page for an updated trainer build before reporting a problem.

- Download the trainer archive from the link on this page.

Important caveats before downloading:
Antivirus false positives: Summer Sisters Trainer contains memory-editing routines that trigger heuristic antivirus warnings — this is a known false positive across the entire trainer/repack category, not actual malware. Each post page links to a VirusTotal scan documenting the false-positive engines.
Online play and bans: Summer Sisters Trainer is for single-player and offline modes only. Online multiplayer modes protected by anti-cheat systems (EasyAntiCheat, BattlEye, VAC, FairFight) detect memory editing — using a trainer online can result in a permanent account ban. Never deploy in competitive online play.
Compatibility note: Summer Sisters Trainer targets the build version listed at the top of this page. After a game patch, an older trainer build typically fails silently — recheck this page for an updated release.
Re-download after major game patches — older trainer builds typically fail silently after offset changes. — FLiNG Trainer 2026
