R-310 is a short-range credit bought rocket. This rocket is most commonly bought by new players due to it being only 100 credits each rocket. Although these rockets are good for taking down most small aliens, one should consider purchasing PLT-2026 rockets or better once you pass your X-2 map. They deal up to 1,000 damage per rocket. The R-310 is one step down from the PLT-2026 rocket.
Short-range rocket: causes up to 1,000 damage points per rocket fired.
