CHRISTIAN_CAINE  This game is a blast. It incredibly addictive but you don't have to play for hours on end to be competitive against other players. An average match only last a few minutes then you can walk away and come back the next day and not miss a thing. Its definitely not a fast paced shooter type game but is still very challenging. You actual have to try to "read" your opponent and outwit them. Strategy and style start to play a huge role as you quickly work up in levels.

Its free.

Its fun.

Its challenging.

Its original.

Highly recommended
