Vindicators - NES - longplay
4Vindicators was not licensed by Nintendo and used an alternate chip to defeat the 10NES lockout system.
Each level has a key that will open a door at the top of the level, which will either take the player to the next level or to a special hub with multiple powerups that must be escaped in 10 seconds or less. (15 for the NES version, though the timer stays stuck at 10 for five seconds before counting.)
