The Red-Sequence Cluster Survey (RCS) is a new galaxy cluster survey designed to provide a large sample of optically selected 0.1$<$z$<$1.4 clusters. The planned survey data are 100 square degrees of two color ($R$ and $z'$) imaging, with a 5$\sigma$ depth $\sim$2 mag past M$^{*}$ at $z=1$. The combined depth and area of the RCS make it the widest field, moderately deep survey ever undertaken using 4m class telescopes. This paper gives a brief outline of the RCS survey, with particular emphasis on the data reduction strategy. The remainder of the paper focuses on preliminary results from the first set of completely reduced data ($\sim$10 deg$^2$, of the $\sim$60 deg$^2$ in hand). We provide a new example of a rich $z>1$ cluster, illustrative of the dozens discovered in the data so far. Some of the possible science to come from the RCS is illustrated by a qualitative indication of $\Omega_{M}$ from the first 1/10th of the survey data. A high-precision measurement of the 2-point correlation function of luminous early-type galaxies at $0.4
