I know some folks here saw this one all over the clearance racks in the late '90s, looked at its stupid, generic cover art, and never thought about it again. If so... hey, me too!
Grid Runner for Saturn or PS1 is a competitive game of capture the flag combined with tag. Perhaps most easily compared to Trap Gunner, the game is played head to head split screen, and each player attempts to touch each of the arena's flags, which changes them to his/her color, before being tagged by the other player. If tagged, the other player begins touching them, undoing your hard work toward their end. Make them all your color to win the match.
You do have weapons and abilities, which do things like slow your opponent down (or neutral enemy hazards), teleport, or build bridges to get across gaps. Games are fun and fast, and very reminiscent of playing Trap Gunner or SNES Mario Kart battle mode in pacing and fun.
I was shocked to discover how much I liked this one, and have had some fun little battle nights with friends with it. Remember seeing it around? Buy it for a buck for a spare Saturn case? Actually play it and have memories?
