Shadowgrounds: Survivor is a standalone expansion to the Shadowgrounds. The game is a top-down shooter with a fast pace and three playable characters, which can upgrade their weapons and attributes in RPG type of fashion. The game is known for its integrated physics, which allows for hundreds of objectives to be destroyed and make the game world alive. In survival mode you basically have to kill survive as long as possible versus the hordes of alien monsters coming at you. Campaign mode is full of action and even more fast-paced than the original game. To see that action for yourself, you can watch the gameplay video provided below.
