Konami Coin-op game?

[tanc24]

I am having the hardest time remembering this game. I am almost certain it is a Konami Coin-Op release, and it is most definitely on this site. I know this because I used to have an unimpressive high score that was recently defeated. My memory tells me it was Dojah who beat it, so maybe he can help refresh my memory.

This game is played from a Top-down perspective. You start out as a guy in a sandy floor/jungle environment, with enemies that pop up out of holes in the ground. You have a gun and grenades. Some guys are hidden in circles of trees that require you to throw the grenades to kill them. I think the guys are kind of mutants of some sort.

It's not much to go on, but it's all I can remember. I want to say the game's name is similar to "Gain Ground", but I know that's not the game. In some regardss it is similar to Gain Ground, for what that's worth.

Thanks in advance for any help!
