Destroy every hostile. Tread Shred is close-quarters tank combat in walled arenas. Steer with the joystick, tap to fire, and use the walls for cover while you line up your shots. Every enemy tank is hunting you too, so reading the angles and staying on the move matter as much as aim. Each kill lands with a freeze-frame, a fireball and a shake you can feel. Every win makes you stronger Every mission pays out coins, and coins buy permanent upgrades. Thicken your armor until your tank shrugs off eight hits, push your firepower to double damage, and tune your speed half again faster. Each track has ten levels, and every upgrade stays with your tank for good, so the mission that beat you yesterday is the one you shred today. Three tiers, no mercy Forty missions make up the Recruit campaign. Clear them all and Veteran unlocks: the same arenas with tougher, faster enemies and double points for every kill and every cleared mission. Clear Veteran and Elite opens up, where enemies are at their toughest and fastest and every score is tripled. Chase the high score Every enemy destroyed is worth 100 points and every mission cleared is worth 500, multiplied by your tier. Keep a run going to push your high score higher, then see where you rank on the Game Center leaderboard, right from the game. Boost when it counts Gems turn a close call into a win. Revive on the spot with full armor when your tank goes down, redeploy into a failed mission with an extra hit, or arm Overdrive to fire two shots per tap until your tank goes down. Every boost shows you a clip of it in action and tells you its cost before you spend. You start with 100 gems, earn more from progress milestones, and can buy packs of 100, 550 or 1,200. Your progress is safe Upgrades, coins, gems and cleared missions back up to iCloud automatically and come back if you reinstall or switch devices.

Verdict
The clearest difference is price: Tread Shred at Free against Shell Shockers's $0.29. Tread Shred also leads on update cadence (fortnightly vs every 33 months). Shell Shockers's advantage is in-app purchases (none vs 4) and iOS requirement (9.0 vs 15.0). On ads and device support there is nothing between them.
