Overdrive 2048 is a 2048 × survivors-like mashup: slide tiles with one hand, mow down swarms with the other.

◆ Merging = Charging: every merge charges your energy bar. A full bar triggers OVERDRIVE — double fire rate, no energy cost, pure carnage. Timing your merges to save overdrive for the deadliest waves is the core skill.

◆ Bullet-heaven combat: mix 15 main weapons with 10 passives, evolve maxed pairs into super weapons, or fuse two maxed mains into devastating fusion weapons. Kill elites to drop treasure chests — spin the slot machine for up to 5 level-ups at once!

◆ Mythic milestone relics: hit 1024, 2048, 4096… each milestone offers a choice of 3 permanent run-wide relics.

◆ Three modes: Quick (10-min chaos), Normal (20-min challenge), Endless (exponential pressure + Steam global leaderboard).

◆ Meta progression: spend coins on 12 permanent upgrades, unlock 8 characters and hidden weapons through achievements — every run makes the next one stronger.
