Evaluation

Super Mutant Alien Assault launched into full release on July 12, 2016 after approximately eleven months in Early Access. The launch post described the game as a finished product, highlighting the "near bottomless pit of unlockable weapons, explosives, sidearms, special abilities, perks and defence moves we have packed into the final product," and introduced a new Endless Mode as the culminating feature of the full release. All developer activity in the news history is either pre-launch Early Access development work (patches and feature updates from August 2015 through January 2016) or the launch announcement itself. The most recent developer post, from July 26, 2018, is solely about the publisher rebranding from Surprise Attack Games to Fellow Traveller — it contains no mention of new content, updates, or future development plans for the game itself. There are no unreleased DLC listings, no roadmaps, no announced expansions, and no post-launch content updates of any kind after the 1.0 release. The game shipped as a complete, finished product and has received no post-launch content additions.

About this game

Three fleets of spaceships flee a doomed Earth carrying the last humans in cryostasis. Pursued by aliens, it’s up to the lowly security droids to save humanity. Taking up arms solo or with a friend, you must dance with death in a brutal and addictive arcade platformer shooter inspired by Super Crate Box and stuffed to the brim with unlockables.

Fight through rapid fire single screen levels each with a random combination of platform layout, objective, vending machines and enemies. Dodge and weave amongst the aliens to stay alive but don’t leave them standing too long or the ship’s radiation will mutate them into bigger, nastier versions.

Only by unlocking and mastering the wild variety of weapons, explosives, special abilities, defense moves and perks can you hope to survive across all three galaxies, rid your ship of the mutant menace and save the oblivious humans.

Features

- rapid fire levels give you no rest as hordes of enemies arrive, hell-bent on your destruction. Clear the objective quickly and be sure to kill each enemy before it has the chance to mutate into a bigger, nastier version of itself. Take a tiny breather and then it’s on to the next room.

- in the tight confines of the space freighter, standing still is not an option. Your ability to dodge around enemies is as important as your aim. Survival requires quick thinking and rapid reflexes and a true master of the dance is a beautiful thing to behold.

- each single screen level is randomised, drawing on a pool of platform layouts, objective types and enemies as well as which vending machines will be present. You’ll never know which weapons or grenades will spawn in the vending machines whilst crate drops containing special abilities, sidearms, perks and defense moves are also random, adding further to the mind-boggling possible combinations.

- a wealth of weapons, sidearms, special abilities, perks, explosives, defense moves and character skins awaits you. Each new unlockable joins the melting pot of random ingredients, increasing your options but also the need to master each individual element and the way they combine with each other.

- take on the mutant hordes by yourself or team up in local co-op. Two player adds further complications to master as you must be careful to avoid friendly fire from explosives and will have to share/fight over item and health pack drops.
