What a fun challenge! Many have been comparing this to Call of Duty Zombies. And while this game is somewhat similar to COD Zombies, it is it's own experience. There are many aspects about this game that make it unique. It is also much more challenging that COD Zombies.
Each time you start a new game, everything you need like ammo, melee weapons, and milk are spawned in different places. This adds to the challenge. I like that the research points are shared between the players. This prevents people from being greedy, which happens a lot in COD. The more you play this game, the better you'll get because you actually level up overtime. This gives this game a lot of re-playability.
Though this is quite the challenge, it had me laughing my way through it. I do hope that eventually this game allows up to 4 players because it would be fun to have the ability to play with even more friends. I'm eager to get some more gameplay under my belt to eventually master this game!
