Rocket jumping
It is a good choice to use ultima cannon to rocketjump around the map. It is possible to obtain the uberhealth by rocketjumping. For those players who are lousy players,they can rocketjump onto one of the bunkers and try to shoot at enemies. Hopefully they will not notice you and you can continue shooting. 
Lost Paradise Classic is a clone of Lost Paradise 1. It has several islands, and two pillars rising from it. The shorter of the pillars is reachable via a Spring Launcher. The Taller can only be reached by placing several Spring Grenades on the trees below, or a single nade while on the shorter pillar.
