Zombie Grinder is the debut game of TwinDrills, an indie game development duo made up of Tim 'Infini' Leonard and Jordan 'Jordizzle' Chewning.
It's a multi-platform (windows, mac, Linux!) (also Free!) cooperative multiplayer arcade game, reminiscent in style and gameplay of retro games like 'Zombies Ate My Neighbors' and 'Super Smash TV!', but with the added benefit of some newer game mechanics - achievements, ranking, player-customization, rpg style stats and so forth.
The game sports a variety of different game modes, from co-operative 'campaign' style levels, to wave maps and even the classic 'pvp' style game modes - deathmatch, capture the 'bag' and so forth. All of these mods are bristling with a variety of weapons and items, all lovingly displayed in Jordan's classic quirky pixel-art style.
Just playing around with some new weapons me and jordan have been putting together;
Requires a few seconds charging time.
When firing you can't stop and your direction is locked.
Can't pickup items or change weapon when firing either.
Most powerful weapon in the game.
Set fire to zombies from far away! Lowest tier of the "fire" weapons.
Fast firing shotgun with a large clip, but with low damage.
Not shown in this video (becuase you need multiple players).
Heals other players.
