Append

Append is a 2D top-down arena shooter with online multiplayer. You control a futuristic hovering space train in a dilapidated space station, fighting other trains as they scavenge. Your roof-mounted cannon gains power-ups stored inside your train cars, which enemies can destroy. Shooting enemies shrinks them and can snipe their abilities; you can build toward offense or defense.

Power-ups and abilities

Collect power-ups and combine them into hundreds of weapon combinations, suited to different situations. Abilities can be upgraded to increase their strength, and mystery boxes let you choose one of three power-ups. The luck power-up increases your chance of finding rare options in these boxes, so you can tailor your arsenal to your opponents.

Power-ups include several types:

• Applicative powers: Add debuffs to enemies. Fire burns over time, water extinguishes fire but helps electricity spread, and snow slows enemies. Higher levels make debuffs stronger or longer-lasting.
• Multiplicative powers: Increase the number of bullets, with variants for precision or mayhem. Higher levels increase the rate of fire.
• Impacting powers: Change what bullets do on impact, such as bouncing, exploding or passing through walls. Higher levels make these effects more prominent.
• Movement powers: Change bullet movement, making shots faster, able to chase enemies, or slower and mine-like. Combining mines with other powers can create defense turrets, and higher levels strengthen the movement effects.
• Passive powers: Improve your chances through effects such as faster movement, healing, luck and train segments that shoot incoming projectiles. Higher levels amplify these effects.

Online multiplayer

Online rooms hold up to ten players. You can create private rooms or let strangers join, and play with friends or other players online. Bots with varying difficulty are available if you do not have enough friends to play with.

Game modes and goals

Modes include free-for-all, where everyone fights everyone, and team play, such as humans versus bots. Goals can vary: grow your train as long as possible, kill the most enemies or shoot the most bullets. Arenas are procedurally generated, and the game is easy to mod.
