Deadlock Highway is a fast, simple arcade driving game where every second on the road gets more intense. Swipe through endless traffic, dodge cars and trucks, squeeze through tight gaps, and push your speed as high as you can. The longer you survive, the faster the highway becomes. Score points for distance, milestones, and dangerous near misses. Crash once and your run is over — unless you use a revive to jump back into the action. Deadlock Highway is built for quick, addictive play sessions. Easy to learn, instantly replayable, and always chasing one more run. Speed increases as your run continues, score bonuses for close calls and milestones. Compete against your best score per mode and difficulty! Features: • Fast endless highway driving • Clean minimalist arcade visuals • 3 control schemes • 3 Game Modes (Classic, Zen and Rush) • 5 Difficulties (Easy, Normal, Hard, Expert, Nightmare) • 4 Pick ups (Brake, Shield, 2x, Bonus Points) How far can you survive the deadlock?
